Sav, you're right in terms of covalently bonding atoms to form stable atoms with 0 overall charge. Ions kinda disrupt that a bit, with such as H3O+ and HO- (the fundamentals of the pH scale of acidity) and others showing hydrogens in odd arrangements.

I wasn't aware of H3+, but... meh. Saying I know chemistry would be like saying that someone who knows that "nation" and "creation" rhyme is a poet.

(edit: Meh. Some 3AM grammar fixed.)
