Covalent bonds occur when atoms share pairs of electrons to form molecules. Atoms form covalent bonds by sharing unpaired valence electrons, with examples being water (H2O) forming two covalent bonds and molecular oxygen (O2) forming a double covalent bond by sharing two pairs of electrons. Properties of covalent bonds include low melting and boiling points with poor conductivity.

Covalent bond
A covalent bond involves the sharing of electron pairs between atoms. There are two types of covalent bonding: non-polar, with equal sharing, and polar, with unequal sharing. A non-polar bond forms between like atoms that share electrons equally, while a polar bond forms between different atoms where one atom attracts the electrons more than the other due to differing electronegativity. Examples of non-polar molecules are H2, Cl2, and O2, where the atoms share electrons equally. Examples of polar molecules are HCl and H2O, where the more electronegative atom (Cl or O) attracts the electrons slightly more, giving it a partial negative charge and leaving the other atom with
Covalent bonds
Covalent bonds form when atoms share electrons to gain a full outer shell. Atoms that form covalent bonds, like hydrogen and oxygen in water, share electrons so that neutral molecules are created. Covalent bonds generally occur between nonmetals and result in molecules with low melting and boiling points that do not conduct electricity well.
Chemical bonding
This document discusses different types of chemical bonds: ionic bonds form when electrons are transferred between atoms, while covalent bonds form when electrons are shared between atoms. Ionic bonds occur between oppositely charged ions and result in crystalline solids with high melting points that conduct electricity when melted. Covalent bonds share electron pairs to achieve stability, and can be nonpolar or polar depending on electron distribution. Compounds formed by covalent bonding exist as gases, liquids or solids with low melting points and poor conductivity. Coordinate covalent bonds involve electron sharing where both electrons come from the same atom. Chemical bonding occurs for atoms to achieve stable electron configurations.
Ionic and metallic bonding
This document discusses different types of bonds:
- Ionic bonds form when a metal transfers valence electrons to a nonmetal, resulting in positively charged metal ions and negatively charged nonmetal ions that are attracted to each other. Ionic compounds are usually solid and brittle with high melting points.
- Covalent bonds form when nonmetal atoms share valence electrons to form molecules. Covalent compounds consist of many molecules.
- Metallic bonds form when metal atoms share their valence electrons, resulting in a "sea of electrons" that surrounds the positive metal ions and allows metals to conduct electricity and heat well.
Chemical bonding
The document summarizes different types of chemical bonds including ionic bonds, covalent bonds, metallic bonds, hydrogen bonds, and Van der Waals interactions. It describes how each type of bond forms and provides examples. Ionic bonds form through electrostatic attraction between oppositely charged ions. Covalent bonds form when atoms share one or more pairs of electrons. Metallic bonds result from delocalized electrons within metal structures. Hydrogen bonds are electrostatic attractions between hydrogen and electronegative atoms. Van der Waals interactions arise from correlations in polarizations between particles.

Chemical bonding Powerpoint
Chemical bonds form when atoms attract each other and bind together. There are three main types of bonds: ionic bonds form when a metal transfers electrons to a non-metal, metallic bonds involve delocalized electrons that move freely between metal atoms, and covalent bonds occur when two non-metals share pairs of electrons. Ionic bonds are strong but brittle, metallic bonds allow metals to conduct heat and electricity, and covalent bonds can be single, double or triple depending on how many electron pairs are shared.
FORMATION OF COVALENT BOND
This document discusses the formation of covalent bonds. It defines covalent bonds as the sharing of electron pairs between nonmetal atoms. There are three types of covalent bonds: single, double, and triple bonds which are formed by the sharing of one, two, or three electron pairs respectively. Examples of bond formation in H2, O2, and N2 molecules are provided to illustrate single, double, and triple bonds. The key differences between ionic and covalent bonds are that ionic bonds involve electron transfer between metals and nonmetals while covalent bonds involve electron sharing between nonmetals.
Chapter 8 Covalent Bonds
1. Covalent bonds form when two atoms share one or more pairs of valence electrons in order to achieve a stable octet of electrons.
2. Molecules are formed when atoms are bonded together by covalent bonds, and molecular compounds are composed of molecules.
3. Molecular compounds tend to have lower melting and boiling points than ionic compounds and many are gases or liquids at room temperature.
Chemical bonding
Chemical bonding can occur through either ionic bonds or covalent bonds. Ionic bonds result from the electrostatic attraction between oppositely charged ions, while covalent bonds form through the sharing of electrons between atoms. The strength of these bonds can vary considerably, from strong primary bonds to weaker secondary bonds.
Metallic Bonding
Metallic bonding occurs when metal atoms lose valence electrons to become positively charged ions embedded in a "sea" of delocalized electrons. This electron sea model explains several properties of metals, including their ability to conduct electricity and heat, as well as their malleability, ductility, lustrous appearance, and high melting and boiling points. The mobile electrons allow for heat and charge conduction, while the metallic lattice structure enables atoms to slide past one another under pressure.
covalent bond
This document discusses properties and uses of covalent compounds. It states that covalent compounds generally have lower melting and boiling points than ionic compounds. They are also more flexible, flammable, and less soluble in water than ionic compounds. The document notes that many fuels, medicines, clothes, and foods contain covalent bonds. It provides examples such as fuels powering daily life and clothes made from covalent materials. Covalent compounds share electrons between nonmetal atoms rather than transferring electrons.
Chemical bonding
This document discusses chemical bonding and the different types of bonds that can form between atoms. It describes how ionic bonds are formed via electron transfer between atoms, and covalent bonds are formed through electron sharing. The octet rule, where atoms gain, lose, or share electrons to achieve a noble gas configuration, is an important concept. Ionic compounds involve the formation of cations and anions, while covalent compounds share electrons between nonmetals. Covalent bonds can be polar, involving unequal electron sharing, or nonpolar with equal sharing. Coordinate or dative bonds also involve electron sharing, but with both electrons coming from the same atom.
Polar Covalent Bond
A polar covalent bond forms when electrons in a covalent bond are not shared equally between the two atoms due to differences in electronegativity. Atoms with large differences in electronegativity will form polar covalent bonds, causing the electrons to be attracted more to the atom with higher electronegativity, such as chlorine in a hydrogen-chlorine bond. Polar covalent bonds result in the atoms having partial positive and negative charges.
Ionic bonds
Ionic bonds form between metal and nonmetal atoms when electrons are transferred. Positively charged metal ions are called cations, and negatively charged nonmetal ions are called anions. Ionic bonds occur when cations and anions are attracted to each other due to their opposite charges, balancing out the overall charge. Ionic compounds write their chemical formulas to represent this charge balance between the ions.
Ionic bonding
Ionic bonds form when a metal transfers an electron to a nonmetal, giving each atom an octet of electrons. For example, sodium loses an electron to form Na+ while chlorine gains that electron to form Cl-. The resulting ions are held together by electrostatic attraction to form an ionic compound, sodium chloride (NaCl). NaCl crystallizes into a repeating pattern where Na+ and Cl- ions alternate in a crystal lattice. Ionic compounds conduct electricity when molten or dissolved due to the movement of ions.
CHEMICAL BONDING AND MOLECULAR STRUCTURE
Chemical bonding can occur via ionic bonds or covalent bonds. Ionic bonds form when electrons are transferred from one atom to another, leaving cation and anion. Covalent bonds form when atoms share electrons via overlapping orbitals. The octet rule states that atoms seek to obtain eight electrons in their valence shell. Hybridization is the mixing of atomic orbitals to form new hybrid orbitals for bonding. Common hybridizations include sp, sp2, and sp3 which determine molecular geometry. Bond properties like order, length, energy are influenced by hybridization.

Metallic bonds and the properties of metals
This document describes metallic bonding and the properties of metals and alloys. It explains that metallic bonding results from the delocalization of valence electrons among metal atoms, forming a "sea" of electrons. Metals are good conductors of heat and electricity due to the mobility of these electrons. The properties of a metal, such as its hardness and melting point, depend on the number of delocalized electrons. Alloys are mixtures of elements that are substitutional, with one metal replacing atoms of another, or interstitial, with smaller atoms filling holes in the metallic crystal structure.

Alloys are mixtures of metals that are generally stronger than their pure metal components due to metallic bonding between different kinds of metal atoms.
Newtons laws
Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Newton's second law states that acceleration depends on the net force acting on an object and its mass. Newton's third law states that for every action there is an equal and opposite reaction. Momentum is the product of an object's mass and velocity, and the law of conservation of momentum states that the total momentum of a system remains constant unless an outside force acts on it.

Chemical bonding project
A chemical bond is the force that holds two atoms together. There are three main types of bonds: ionic, covalent, and metallic. Ionic bonds form between oppositely charged ions and result in compounds with high melting and boiling points that conduct electricity when dissolved in water. Covalent bonds form when atoms share one, two, or three pairs of electrons to achieve stable electron configurations, with stronger bonds having shorter lengths. Metallic bonds result from the delocalization of electrons between metallic cations, allowing metals to conduct heat and electricity well.

Forces in fluids
This document discusses various principles related to forces in fluids. It explains that pressure relates to force over an area and is greater the deeper one is in a fluid. Objects will float if their density is less than the fluid and sink if greater. Buoyancy creates an upward force opposing gravity. Archimedes' principle states buoyant force equals weight of displaced fluid. Pascal's principle explains how pressure changes in confined fluids are transmitted equally. Bernoulli's principle describes decreasing pressure as fluid speed increases.
Energy
Energy is the ability to do work or cause change. There are two main types of energy: kinetic energy, which is the energy of motion, and potential energy, which is stored energy due to an object's position or shape. The law of conservation of energy states that energy cannot be created or destroyed, but can change forms.
Motion etc
This document defines and explains key concepts related to motion, speed, velocity, and acceleration in physics. It defines motion as the changing distance between objects based on a reference point. Speed is defined as the distance traveled over time, while velocity includes both speed and direction of motion. Acceleration is defined as the rate of change of velocity over time, which can refer to increasing or decreasing speed or changing direction. Examples and calculations are provided for each term.
Notes nebula starlife
The document summarizes the life cycle of stars from their birth in nebulae through their evolution into red giants, white dwarfs, neutron stars, or black holes. It explains that stars produce light through nuclear fusion, where hydrogen fuses into helium. Nebulae are large clouds of dust and gas where stars are born as gravity causes material to collapse and form protostars at the center.
Star Classification
Stars are large balls of ionized gas held together by gravity that emit energy through nuclear reactions. They are classified based on size, temperature, and brightness. Size categories include super giants, red giants, main sequence, white dwarfs, and neutron stars. Temperature determines color, from red (coolest) to blue (hottest). Brightness depends on both a star's intrinsic luminosity and its distance from Earth. Spectrographs are used to analyze starlight and determine properties like chemical composition, temperature, and distance.
Asteroids, comets, meteors
Asteroids are rocky objects that orbit the sun and are smaller than planets. Comets are made of ice and dust with elongated orbits around the sun, forming tails as they near the sun. Meteors enter Earth's atmosphere as meteorites and appear as "shooting stars", transitioning from meteoroid to meteor to meteorite. While both appear as streaks of light, comets remain stationary while meteors quickly streak across the sky.
Keplers laws
Early Greek astronomers believed in a geocentric model of the universe, with Earth at the center. Ptolemy hypothesized that planets moved in circular orbits around Earth. Nicolaus Copernicus later developed a heliocentric model placing the Sun at the center. Johannes Kepler analyzed astronomical data collected by Tycho Brahe, leading Kepler to discover his three laws: 1) planetary orbits are ellipses rather than circles, 2) planets move faster when closer to the Sun and slower when farther, and 3) the squares of planetary orbit periods are proportional to the cubes of their average distances from the Sun.
Keplers laws
The document discusses the history of models of the solar system from ancient Greek astronomers to Johannes Kepler. It describes how Greeks originally believed in a geocentric model with the Earth at the center, which was later supported by Ptolemy. Copernicus then developed the heliocentric model of the sun at the center. Galileo's observations of Jupiter's moons and use of the telescope supported this model. Tycho Brahe and Kepler collected extensive observational data, allowing Kepler to develop his three laws: planets orbit in ellipses, their speed changes as they revolve with closer planets moving faster, and their orbital period relates to their average distance from the sun.
Notes on our solar system
Our solar system contains 1 sun, 8 planets, 5 dwarf planets, and over 170 moons. The planets are divided into two groups - terrestrial planets which are small and rocky, and gas giants which are much larger and composed primarily of hydrogen and helium. Terrestrial planets include Mercury, Venus, Earth, and Mars. Gas giants include Jupiter, Saturn, Uranus, and Neptune. Dwarf planets such as Ceres and Pluto have not cleared their orbital path. Pluto was reclassified as a dwarf planet after astronomers discovered other similar objects in the Kuiper belt.
Sun, Earth, Moon System
This document discusses the relationships between planets, moons, and other celestial bodies. It explains that the Moon orbits the Earth and is considered our natural satellite. A satellite revolves around a planet. Lunar eclipses occur when the Moon passes behind Earth into its shadow, while solar eclipses happen when the Moon passes between Earth and the Sun. The Moon's phases are caused by varying amounts of sunlight reflecting off its surface due to its orbit around Earth. Tides are also influenced by the Moon's gravity, with high and low tides occurring regularly due to the positions of the Moon and Sun relative to Earth.
Notes revolution rotation
This document provides an overview of key astronomy concepts including:
- The structures of the solar system such as the sun, planets, and moons.
- Key terms like axis of rotation, period of rotation, period of revolution, and ellipses that describe planetary motion.
- Distances in our solar system measured in Astronomical Units and on a galactic scale using light years.
- How the tilt of the Earth on its axis and its revolution around the sun cause the seasons.
- The equinoxes in March and September when day and night are equal length and the solstices in June and December when the sun is farthest from the equator.
CHONPS (basic o-chem intro)
Carbon plays a central role in living organisms due to its ability to combine with itself and other elements in many ways. Organic compounds contain carbon and were originally thought to only relate to living things, but are now known to exist more broadly. Polymers are long chains of molecules formed when monomers link together repeatedly through chemical bonds, and include both synthetic materials like plastics as well as natural polymers like proteins, DNA, and silk that make up living things.
Acids bases
The document discusses acids, bases and the pH scale. It explains that the pH scale ranges from 0-14 and measures the concentration of hydrogen ions in a solution. Acids have a pH below 7 and contain hydrogen ions, while bases have a pH above 7 and contain hydroxide ions. A pH of 7 is neutral. The document also provides examples of common acids and bases, their properties, and some of their uses.
Balancing equations
The document discusses how to balance chemical equations by ensuring the total number of atoms on both sides of the equation are equal. It explains that coefficients are used to represent the number of molecules in a reaction, while subscripts indicate the number of atoms in a molecule. The steps to balance an equation are to: 1) Write the unbalanced equation, 2) Count the atoms on each side, 3) Use coefficients to make the atoms equal on both sides. Examples are provided to demonstrate balancing equations through adjusting coefficients and verifying the balanced atoms.
Chemicall change
This document discusses observing and describing chemical changes. It defines chemical and physical properties and changes. A chemical change results in a new substance, while a physical change only changes the appearance or form of a substance. Chemical changes involve reactants changing into products and can be represented by chemical equations. They involve breaking and forming bonds. Evidence of a chemical change includes new properties, energy changes, and conservation of mass, with the same number and types of atoms in the reactants and products. A system can be open or closed to matter flow during chemical reactions.
Chemical reactions
This document summarizes key concepts about chemical reactions and properties. It defines chemical properties as the ability of a substance to change into a new substance, and physical properties as observable characteristics that do not change the substance. Chemical changes result in new substances, while physical changes alter appearance but not substance. For a chemical reaction to occur, bonds must be broken and reformed, allowing atoms to rearrange. Signs that a chemical reaction has taken place include formation of a precipitate, release of heat or light, and changes in color, temperature or gas formation. Chemical equations balance reactants and products to obey the law of conservation of matter, where mass and atoms are conserved despite rearrangement during bonding changes. Reaction rates depend on factors like activation energy
Periodic table
The document summarizes the history and organization of the periodic table. It describes how Mendeleev organized the first periodic table based on atomic mass and properties, and how the modern table is organized by atomic number. The periodic table is divided into periods and groups; elements in the same group have similar properties. The document also defines metals, nonmetals, semimetals, and inert gases, and provides examples of their characteristic properties.
Ionic bonds
Ionic bonds form between metal and nonmetal atoms when the metals donate electrons to the nonmetals, becoming positively charged cations while the nonmetals accept electrons and become negatively charged anions. The oppositely charged ions are then attracted to each other, bonding ionically. When ionic compounds form, the charges balance out according to the formula. For example, two chloride (Cl-) ions with a charge of -1 each will balance out one magnesium (Mg2+) ion with a charge of +2, written as MgCl2. Ionic compounds form hard, brittle solids with high melting points and conduct electricity when dissolved in water.
Isotopes, Lewis Dot Diagrams and Predicting Reactions
This document provides a review of key concepts related to isotopes, Lewis dot diagrams, and predicting chemical reactions. It defines isotopes as variants of the same element with different numbers of neutrons. Lewis dot diagrams represent valence electrons and allow prediction of how atoms will react to gain or lose electrons to achieve stable full outer shells like noble gases. Atoms react in the simplest way possible to satisfy this rule by losing or gaining the fewest electrons.
Bohr diagrams
This document discusses the key parts of an atom including atomic number, mass, protons, neutrons, and electrons. It explains that the atomic number tells us the number of protons and it shows how to calculate neutrons by subtracting the atomic number from the atomic mass. The number of electrons is the same as the number of protons to maintain neutral charge. It demonstrates this process for carbon and neon atoms and teaches how to draw Bohr diagrams showing the nucleus and electron shells.
