Lattice Energies are always given as negative numbers

SIZESmaller ion ===> more lattice energy

Larger ion ===> less lattice energy

CHARGELarger (+ or -) ===> more lattice energy

Covalent Bonding Tutorial as introto COVALENT BONDING STD 2

http://youtu.be/ZYrzHU7EpNM

Rules for drawing Lewis Structures of covalently bonded molecules

1. All atoms must have 8 of the available valence electrons

(octet rule)

2. At the end, check to see that all of the valence electrons have been used
