Chemical bonding
Gilbert Lewis proposed that chemical bonds form between atoms through the interaction of electrons from different atoms. He observed that many elements are most stable when they have eight electrons in their valence shell, which can be achieved through the transfer or sharing of electrons. This leads to the formation of two main types of chemical bonds - ionic and covalent bonding. Ionic bonding involves the combination of oppositely charged ions, where one atom gains electrons to become negatively charged and another loses electrons to become positively charged. These ions are held together by electrostatic forces to form ionic compounds such as sodium chloride.
powerpoint presentation
Ionic bonds form when one atom gives up electrons to another atom, resulting in ions of opposite charge attracting one another. Covalent bonds involve the sharing of electron pairs between atoms. Metallic bonds are formed from the attraction between mobile electrons in metals and the fixed positive metallic atoms. A coordinate covalent bond is produced when one atom shares an electron pair with another atom that is lacking a pair.
Chemical bonding
There are three main types of chemical bonds: ionic, covalent, and metallic. Ionic bonds form when electrons transfer from a metal to a non-metal, resulting in oppositely charged ions. Covalent bonds form when atoms share one or more pairs of electrons to achieve an octet. Metallic bonds form through delocalized electrons that are free to move throughout the metal lattice, allowing metals to conduct electricity and have high melting points.
Ionic compound
Ionic bonding occurs when valence electrons are transferred from metal atoms to non-metal atoms, resulting in positively charged cation and negatively charged anion ions that are attracted via electrostatic forces. Ionic compounds form when a metal donates its valence electrons to a nonmetal. The electrostatic attraction between opposite charges holds the ions together. Common ionic compounds include sodium chloride, formed from sodium cations and chloride anions, and magnesium oxide, formed from magnesium cations and oxide anions.
Chemical Bonding - 1
The document discusses electronegativity and types of chemical bonding. Electronegativity is the ability of an atom to attract shared electrons, and the difference in electronegativity between two atoms determines the type of bond formed. There are three main types of bonds - covalent, ionic, and metallic - which give compounds different physical properties such as state, melting/boiling points, conductivity, and solubility. The document also lists topics to cover in more depth related to chemical bonding concepts.
Types of Chemical bonds
This document provides an overview of different types of chemical bonds: ionic bonds, covalent bonds, coordinate covalent bonds, and metallic bonds. It defines each bond type, provides examples, and notes some key properties. Ionic bonds form when a metal transfers an electron to a nonmetal. Covalent bonds form through the sharing of electrons between two nonmetals or between atoms of different elements. Coordinate covalent bonds involve the sharing of an electron pair donated by one atom. Metallic bonds form a "sea of electrons" that holds metallic cations together. The document aims to clarify the concept of chemical bonding.
C2.1 structure and bonding
Ionic compounds form giant lattice structures when oppositely charged ions bond via electrostatic forces. This ionic bonding results in high melting points and the ability to conduct electricity when molten or dissolved. Covalent bonds involve electron sharing and can form either simple molecules with weak intermolecular forces or giant covalent structures with very high melting points due to numerous strong covalent bonds. Metallic bonding involves delocalized electrons that act as glue between positive metal ions, allowing them to slide past one another.
Ionic bonds
According to Gilbert Lewis, atoms combine i order to achieve a more stable electron configuration. Maximum stability is obtained when an atom is isoelectronic with a noble gas. This presentation would enable students to relate lattice energy with physical properties such as melting point.

Chemical bonds hold atoms together in compounds and determine compounds' properties. Compounds have definite compositions and properties unlike their constituent elements. Ionic bonds form when atoms transfer electrons to become ions of opposite charge, binding in crystalline structures. Covalent bonds form when atoms share electron pairs, binding as individual molecules with properties depending on size and shape. Metallic bonds allow electron delocalization in metal crystals. Different bonding structures give compounds distinctive physical and chemical characteristics.
7 polar and nonpolar molecules almocera & almocera
This document discusses polar and nonpolar molecules based on electronegativity differences between bonded atoms. It explains that a bond is nonpolar if the electronegativity difference is less than 0.5, polar covalent if the difference is between 0.5 and 2.0, and ionic if the difference is greater than 2.0. It uses the examples of H2, HF, and NaF to illustrate these bond types, noting that H2 has equal sharing, HF has unequal sharing leading to a polar bond, and NaF has full electron transfer and an ionic bond formed by electrostatic attraction between ions.
nature of bonding of chemistry
- Organic chemistry involves carbon-based compounds, with hydrogen usually being the second most common element. Other common elements are oxygen, nitrogen, sulfur, and halogens.
- Most bonds in organic compounds are covalent, formed through shared electron pairs between atoms. Whether bonds are ionic or covalent depends on the electro-negativity difference between bonded atoms.
- Polar covalent bonds form when there is some electro-negativity difference between atoms, causing the electron cloud to shift slightly towards the more electronegative atom. This gives the atoms partial positive or negative charges.
Chemical bonds
This document discusses different types of chemical bonds: ionic bonds form when atoms gain or lose valence electrons to become ions with opposite charges that attract.

Periodic Trends
Dimitri Mendeleev was the first to publish an organized periodic table of elements in 1869. He understood the periodic law - that elements arranged by atomic number display a repeating pattern of chemical and physical properties in vertical columns due to their valence electrons. Mendeleev even predicted properties of undiscovered elements, which were later confirmed. The periodic table shows trends in atomic radius, ionization energy, electron affinity, and electronegativity that relate to chemical reactivity. Metals are on the left and are characterized by properties like conductivity, while nonmetals are on the right and have opposing properties.

2016 topic 4.2 bonding - covalent
This document provides an overview of ionic bonding. Ionic bonds form between elements when one atom loses electrons to become a positively charged ion and another atom gains those electrons to become a negatively charged ion. For example, in sodium chloride, sodium atoms lose electrons to form Na+ ions and chloride atoms gain electrons to form Cl- ions. The oppositely charged ions are then held together by electrostatic forces in a repeating crystal lattice structure. Ionic compounds have high melting points, are brittle, and do not conduct electricity in solid form but do conduct when molten or dissolved in water as the ions become mobile.
Chemical bonding
There are three main types of chemical bonds: ionic bonds, covalent bonds, and metallic bonds. Ionic bonds form between oppositely charged ions, such as between sodium and chlorine atoms where sodium loses an electron to become positively charged and chlorine gains an electron to become negatively charged. Covalent bonds form when atoms share electrons, such as in water where oxygen and hydrogen share electron pairs. Metallic bonds form by the attraction of free-floating electrons within a lattice of positive metal ions.

Subject: Chemical Bonding in physics....
This document discusses different types of chemical bonds:
- Ionic bonds form between metals and nonmetals through the transfer of electrons to create positively and negatively charged ions. Covalent bonds form between nonmetals through the sharing of electron pairs to create molecular compounds. Metallic bonds involve the pooling of electrons between metal atoms. Polar bonds occur when electrons are shared unevenly between atoms. Understanding chemical bonds is important because they join atoms in the materials used in everyday life.
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.
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.
OCTET RULE (TYPES OF CHEMICAL BONDING) .pptx
Everyone seeks stability, which refers to resistance to change. Atoms also seek stability by obtaining a noble gas electron configuration with 8 outer electrons through bonding. The Lewis bonding theory states that atoms bond by transferring or sharing electrons to achieve stable configurations. There are different types of bonds including ionic bonds between metals and nonmetals formed by electron transfer, and covalent bonds between nonmetals formed by electron sharing to obtain octets.

It describes the types of chemical bonds including ionic bonds formed by electron transfer, covalent bonds formed by electron sharing, and polar covalent bonds where bonding electrons are shared unequally. Metallic and coordinate covalent bonds are also discussed. The document explains ion formation and gives examples of naming and writing formulas for ionic and covalent compounds.
Chem unit 6 presentation
Ionic bonds form when oppositely charged ions attract each other, forming ionic compounds. Cations form when atoms lose electrons to achieve a stable electron configuration, while anions form when atoms gain electrons. Ionic compounds consist of a crystal lattice structure where cations are surrounded by anions. They have properties like high melting points and boiling points since energy is required to overcome the strong electrostatic attractions between ions.
Chemical Bonds
This document discusses different types of chemical bonds including ionic bonding, covalent bonding, and metallic bonding. Ionic bonding involves the electrostatic attraction between oppositely charged ions when atoms gain or lose electrons. Covalent bonding occurs when atoms share pairs of electrons to gain stability. Metallic bonding results from the attraction between positively charged atomic nuclei and delocalized electrons in metals that act as the binding medium. The importance of chemical bonding is that it allows atoms to join together to form molecules and structures with unique physical and chemical properties essential for life.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Chemical bonding
- 1. Mrs. Leah Mae C. Mojar Science Teacher
- 3. Who proposed the chemical bonds? GILBERT NEWTON LEWIS - an American chemist who proposed that the chemical bonds are formed between atoms because electrons from the atoms interacts with each other.
- 4. GILBERT NEWTON LEWIS - observed that many elements are most stable when they contained eight electrons in their valence shell like that of the noble gases - condition is attained by atoms either by transferring or sharing electrons - two processes of forming the two main types of chemical bonding: ionic and covalent bonding
- 5. IONIC BONDING It involves the combination of ions of opposite charges
- 6. - are positively-charged atoms which are formed when an atom loses electrons. The charge depends on the number of electrons the atom lost
- 7. - are negatively-charged atom which are formed when an atom gains electrons. The charge depends on the numbers of electron the atom gained.
- 8. NaCl a positively-charged Sodium ion (left) and a negatively-charged Chlorine ion (right)
- 9. Sodium Metal + Chlorine gas Table salt Sodium Metal – is a very reactive metal. It reacts violently and it produces flame once it gets wet. Chlorine – is a poisonous gas used as a weapon in World War I.
- 10. The compounds formed are called ionic compounds. After the reaction takes place, the + and Cl- ions are held charged Na together by electrostatic forces, thus forming an ionic bond.
- 11. FEATURES OF IONIC COMPOUNDS • Ionic compounds form between metals and naming simple ionic compounds, the • In non-metals. metal is always given first, the non-metal (i.e., Sodium chloride) • Ionic compounds dissolve easily in water and other polar solvents. • In solutions, ionic compounds easily conduct electricity. • Ionic compounds tend to form crystalline solids with high melting temperature. * END OF REPORT *
