PPT-Chapter 8 – Basic Concepts of Chemical Bonding

Jennie L Borders Section 81 Chemical Bonds Lewis Symbols and the Octet Rule Whenever two atoms or ions are strongly attached to each other we say there is a chemical bond between them There are three general types of chemical bonds ionic covalent and metallic. Molecular Geometry. Ch. 6 Sections 1-4 Review. In general, what determines whether atoms will form chemical bonds?. Atoms will form a chemical bond if their potential energy is lowered in doing so.. Describe the difference between ionic and covalent bonding.. 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.. CHEMICAL BOND – A force that holds two or more atoms together as a unit. Individual atoms will naturally bond together to achieve a lower energy state (to be more stable). 3B-1 (of 42). TYPES OF BONDS. Molecular Shapes. VSEPR Theory. From a correct Lewis structure, we can get to the 3-D shape using this theory.. VSEPR stands for . v. alence . s. hell . e. lectron . p. air . r. epulsion.. The theory is based on the idea that e- pairs want to get as far away from each other as possible!. This topic will be investigated under five main headings:. Chemical Compounds. . Ionic Bonding. . Covalent Bonding. Electronegativity. . Shape of Molecules and Intermolecular forces.
