PPT-COVALENT BONDING 1 Chemical Bond

A Quick Review A bond results from the attraction of nuclei for electrons All atoms are trying to achieve a stable octet IN OTHER WORDS the protons in one nucleus are attracted to the electrons . and . Electronegativity. Presented by . Leticia Bonita Prince. Newcastle University 4. th. Year . MChem. Student. Aims of Today. Increase your understanding of bonding and electronegativity. Increase your spatial skills and awareness using software designed by the CCDC. Introduction to Chemical Bonding. Introduction to Chemical Bonding. Objectives:. Define . chemical bond.. Explain why most atoms form chemical bonds.. Describe ionic and covalent bonding.. Explain why most chemical bonding is neither purely covalent nor purely ionic.. VSEPR Theory, Polarity, and using . Electronegativity. Covalent . Bonds. Forms when 2 atoms share a pair of valence e. -. A. Types of Covalent Bonds. 1. . Single Covalent Bond . – two atoms share . Co = Together. The Octet Rule. The octet rule says that all atoms want to have eight valence electrons, like the noble gases.. One way that atoms can follow the octet rule is by giving and taking electrons… ionic bonding. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces. Chemical Compounds. There are two kinds of pure substances. Elements. Compounds. Let’s start the new notes…. Elements.

OBJECTIVES:. Prepared By:-. Swastik Mishra Upasana Nath. Rahul Kanungo Pratik Patnaik. 1. st. Shift. Kendriya Vidyalaya No-1, . BHubaneswar. Kossel Lewis Approach. Kossel Lewis Approach To Chemical Bonding. In 1916, Kossel and Lewis were the first to become independently successful in giving a satisfactory explanation about the formation chemical bond in terms of electrons. . Covalent Bonding. A . chemical bond . is the force that holds two atoms together and makes them function as a unit. Atoms form bonds to become most stable and obtain an octet. Covalent Bonding: Electrons are shared between two or more elements. Always between 2 non-metals. Jennie L. Borders. Section 8.1 – Molecular Compounds. A . covalent bond. is formed between atoms held together by . sharing. electrons.. A . molecule. is a group of atoms joined by . covalent bonds. Covalent bonds . result from the . sharing . of electrons. between two atoms.. A covalent bond is a . two-electron bond . in which the bonding atoms share valence electrons.. A . molecule . is a discrete group of atoms held together by covalent bonds.. Types of Chemical Bonds. Ionic bonds. : attraction between positive and negative ions (e- are lost or gained. ). m. etal + nonmetal (K. 2. O). Covalent bonds. : . sharing. of electrons between two . The Covalent Bond. Section 9.1. Worldwide, scientists are studying ways to increase food supplies, reduce pollution, and prevent disease. Understanding the chemistry of compounds that make up fertilizers, pollutants, and materials that carry genetic information is essential in developing new technologies in these areas. An understanding of the chemistry of compounds requires an understanding of their bonding..
