CHEM 1A Chapter Notes - Chapter 9: Bond Energy, Chemical Bond, Ionic Bonding
Document Summary
Chapter 9 - chemical bonding i: the lewis model (pp. Ionic bonding: lewis symbols and lattice energies (p. 384) Lewis structures of molecular compounds and polyatomic ions (p. 398) Exceptions to the octet rule: odd-electron species, incomplete octets, and expanded octets (p. 406) Bonding in metals: the electron sea model (p. 413) Key concepts: bonding models and aids drugs (9. 1) Theories that predict how and why atoms bond together are central to chemistry because they explain compound stability and molecule shape. Bonding theories have been useful in combating hiv because they help in the design of molecules that bind to the active site of a protein crucial for the development of aids: types of chemical bonds (9. 2) We can divide chemical bonds into three general types: ionic bonds, which occur between a metal and a nonmetal; covalent bonds, which occur between two nonmetals; and metallic bonds, which occur within metals.
