Document Summary

Ionic bonds: bonds that are due to electrostatic attractions between oppositely charged ions. Covalent bonds: where molecules are formed by the sharing of electrons between atoms. Metallic bonds: formed by electrons that are relatively free to move through the metal. Lewis symbol: consists of an elements chemical symbol plus a dot for each valence electron. Octet rule: atoms tend to gain, lose, or share electrons until they are surrounded by eight valence electrons. Ionic bonding involves a metal and a nonmetal where the electron from the metal is transferred to the metal. Lattice energy: the energy required to completely separate a mole of solid ionic compound into its gaseous ions. Transition metals lose valence shell s electrons first, then as many d electrons as are required to reach the charge of the ion. Chemical bond formed by sharing a pair of electrons is a covalent bond.
