Distinguish ionic, covalent, and metallic bonding by describing the particles and electrostatic attractions involved.

Use valence electrons to predict the number of bonds formed by common non-metal atoms.

Draw Lewis structures for simple neutral molecules containing single bonds and lone pairs.

Draw Lewis structures for simple molecules containing double or triple bonds.

Draw Lewis structures for simple polyatomic ions using brackets and overall charge.

Check a Lewis structure by counting bonding and non-bonding electron pairs around each atom.

Explain the difference between intramolecular bonds and attractions between separate particles.
