So polyatomic ions are several atoms covalently bonded to one another but having a positive or negative charge because the total number of valence electrons from the atoms cannot produce a stable structure. with one or more electrons added or removed, a stable structure results.
example: nitrate
knowing this, why do compounds need to be neutral while polyatomic ions not. why don't compounds follow the same strategy as polyatomic ions such that they add or remove electrons to make themselves stable?
