This document summarizes key concepts from Chapter 7 on ionic and metallic bonding. It discusses how ions form as atoms gain or lose electrons to achieve stable noble gas electron configurations. Cations are positive ions that form when metals lose electrons, while anions are negative ions that form when nonmetals gain electrons. Ionic compounds consist of cations and anions bonded through electrostatic attraction. Metals form metallic bonds where valence electrons are delocalized and allow the structure to be malleable.

Chapter 6.3 : Ionic Bonding and Ionic Compounds
Ionic compounds are composed of positive and negative ions in ratios that balance the charges. They form crystalline lattices with ions arranged in an orderly pattern. The ions are held together by strong electrostatic forces called lattice energy. Ionic compounds have high melting and boiling points, are hard and brittle, and conduct electricity when molten or dissolved but not in the solid state. Polyatomic ions are charged groups of covalently bonded atoms that behave as single ions in ionic compounds.

Chemical bonds
Chemical bonding involves the attraction between atoms that forms as a result of interactions between valence electrons. There are three main types of bonds: ionic bonds result from the transfer of electrons between metals and nonmetals, covalent bonds involve sharing of electrons between nonmetals, and metallic bonds are attractions between positive metal ions and delocalized electrons in metals. The number of valence electrons determines an element's chemical properties and how it bonds. Chemical reactions occur through the breaking and forming of new bonds, and equations are used to represent these processes in a balanced way that obeys the law of conservation of mass.
Ions & Isotopes
Isotopes are atoms of the same element that have different numbers of neutrons, while ions are atoms or groups of atoms that have gained or lost electrons, giving them a positive or negative charge. Ions are formed by gaining or losing electrons, not protons. Cations are positively charged ions formed when atoms lose electrons, such as metals, while anions are negatively charged ions formed when nonmetals gain electrons. The periodic table can be used to predict which elements will form cations or anions based on their group.
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.
Bonding Basics
This document provides an overview of bonding basics, including ionic and covalent bonds. Ionic bonds form when a metal transfers electrons to a nonmetal, resulting in oppositely charged ions that attract. Covalent bonds form when atoms share electrons to achieve a full outer shell.

Chemical bonding
The document discusses different types of chemical bonding:
1) Ionic bonding occurs when atoms transfer electrons to form ions that are attracted via opposite charges. Ionic compounds form crystal lattices and are hard, brittle, and have high melting points.
2) Covalent bonding occurs when atoms share electrons, forming either polar or nonpolar bonds. Covalent compounds have weaker attractions and are typically liquids, gases or network solids. They have low melting points and conduct limited electricity.
3) Valence electrons are those in the outermost shell that form bonds. The Lewis structure model represents these electrons with dots.
ionic bond
1) Atoms are made up of electrons, protons and neutrons. Electrons occupy electron shells and determine how an atom bonds with other atoms.
2) Ionic bonds form when a metal transfers electrons to a nonmetal, giving them opposing charges. For example, sodium (Na) transfers an electron to chlorine (Cl), forming sodium ion (Na+) and chloride ion (Cl-).
3) Covalent bonds form when atoms share electrons to fill their outer electron shells in a stable configuration.
Bonds
A bond is formed when two or more atoms join together through sharing or exchanging electrons to achieve stability. A molecule is two or more bonded atoms, and a substance can be either a pure element or compound made of two or more elements. There are two main types of bonds: covalent bonds formed by sharing electrons between nonmetals and ionic bonds formed by a transfer of electrons between a metal and nonmetal. The periodic table arranges elements and can provide information about their valence electrons and reactivity through bonding properties.
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.
Chemistry - Chp 8 - Covalent Bonding - PowerPoint
The document summarizes key concepts about covalent bonding from a chemistry textbook chapter:
1) Covalent bonds form when two nonmetal atoms share one or more pairs of electrons to achieve a noble gas configuration, forming molecules like H2, O2, and CO2.
2) Molecular compounds formed by covalent bonds tend to have lower melting and boiling points than ionic compounds due to the weaker nature of the covalent bond.
3) Electron dot structures and Lewis diagrams are used to represent how atoms share electrons to form single, double or triple covalent bonds in molecules like H2O and NH3.
Introduction to Chemical Bonds
Atoms form ions by gaining or losing electrons to achieve a full outer electron shell like noble gases. Ions then bond to form ionic compounds between metals and nonmetals like NaCl. Covalent bonds form when atoms share electrons to achieve full outer shells, like in H2O. Polyatomic ions, which are ions of two or more bonded atoms, can also participate in ionic bonding, such as Ca(OH)2 which contains hydroxide ions bonding to calcium ions. The number of each type of atom in a compound is shown by subscripts based on the ions formed.

chemical bonding
Atoms form bonds to attain a lower potential energy state. They do this through ionic bonds, where oppositely charged ions attract, or covalent bonds, where atoms share valence electrons. Whether a bond is ionic or covalent depends on the electronegativity difference between the atoms. Ionic bonds form between metals and nonmetals, while covalent bonds form between two nonmetals. Lewis structures use dots to represent valence electrons and show how atoms share electrons to achieve stable configurations like noble gases.

Ions form when atoms gain or lose electrons to achieve stable noble gas configurations. Ionic compounds consist of cation and anion ions with opposite charges that are attracted via ionic bonds. Metals form crystalline structures with mobile valence electrons that provide conductivity and malleability. Alloys combine elements to produce superior properties.
What is an ion? - Chemistry presentation
An ion is an atom or molecule that has gained or lost electrons, giving it a positive or negative charge. Atoms can become ions through ionization, where metals typically lose electrons to form cations and nonmetals gain electrons to form anions. Ionic compounds are formed when oppositely charged ions bond via ionic bonds, while covalent bonds involve the sharing of electron pairs between nonmetal atoms.
Chemchapt7 101015133424-phpapp01
Ionic compounds are formed when oppositely charged ions attract each other. Metals form ionic bonds with nonmetals and crystal lattices. In ionic compounds, the cation is written first followed by the anion to give an electrically neutral compound. Polyatomic ions and oxyanions contain multiple atoms bonded together with oxygen. Metallic bonds are delocalized electrons that are shared between positive metal ions in a crystal lattice.
Core Bonding - Ionic Bonding.pptx
Ionic bonds form between metal and non-metal atoms through the transfer of electrons. Metal atoms donate electrons to form cations, while non-metals accept electrons to form anions. The resulting electrostatic attraction between the oppositely charged ions constitutes the ionic bond. Common examples provided are the formation of NaCl through Na donating an electron to Cl, and MgO through Mg donating two electrons to O. Ionic compounds exist as giant crystalline lattices held together by these ionic bonds. Significant energy input is required to overcome the electrostatic forces and break the bonds.

Chemical bonding by_rohit_raj_ranjan
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bond
Chemical Bonding Part 1
A chemical bond is a force that holds atoms together, causing them to function as a single unit. There are three main types of bonds: ionic bonds, polar covalent bonds, and covalent bonds. Ionic bonds form between a metal and nonmetal when electrons are transferred from one atom to the other, creating oppositely charged ions. Polar covalent bonds involve the unequal sharing of electrons between two nonmetals. Covalent bonds equally share electrons between two nonmetals. Bonds are important because they determine how atoms interact and undergo chemical reactions.

The document gives an example of a Sankey diagram for electric power production that shows how much energy is wasted versus transferred to consumers. It also provides the equation for calculating efficiency based on useful energy transferred versus total energy supplied.
P3 RADIOACTIVE MATERIALS
The document discusses radioactive waste and radioactive decay. It defines radioactive waste as material containing unusable radioactive byproducts from nuclear processes. It describes three types of radioactive waste - low-level waste, intermediate-level waste, and high-level waste. It also explains the three types of radioactive decay - alpha decay, beta decay, and gamma decay.
WEATHERING OF ROCKS
The document discusses the process of weathering and how it breaks down rocks into smaller pieces through natural forces. It defines weathering as the process by which natural forces break down rocks. It provides examples of how factors like heating and cooling, wind, and acid rain from air pollution can cause weathering by breaking rocks down over time through physical and chemical breakdown. Acid rain occurs when gases like sulfur dioxide and nitrogen oxides react with water to form acids that fall as rain, and it can enhance the chemical weathering of rocks and statues.
NATURAL SATELLITE (THE MOON)
The document discusses the moon and its phases. It begins by asking students to discuss what they know about the moon with a partner. It then provides information about the moon, including that it is Earth's only natural satellite, the largest relative to its planet, and non-luminous. The document discusses the different phases of the moon, which are caused by the changing angles between the sun, Earth and moon. Students learn that half the moon is illuminated by the sun at any time.
CHANGING EARTH
The document discusses the structure of the Earth and how volcanoes are formed. It explains that the Earth has four distinct layers - an inner solid core, outer liquid core, molten mantle, and outer solid crust. Magma is melted rock found under the Earth's surface in the mantle. Volcanoes are formed when magma escapes through the crust from the mantle.

Understanding Ionising Radiation
Ionising radiation comes from radioactive materials and can damage human cells. There are three main types: alpha particles, beta particles, and gamma rays. Alpha particles are the largest but easiest to stop, while gamma rays are smallest but hardest to stop. Radioactive decay occurs as unstable atoms emit radiation and become more stable. Each type of decay changes the atom in a different way. Ionising radiation is dangerous as it can damage DNA in human cells and lead to cancer or genetic defects.
