i don't really get the idea of what a poly atimic ions is. i couldn't understand the meaning from my textbook. can u plz explain it to me.
poly atomic: make of more than one atom
CO3 is an example
polyatomic ion: made up of more than one atom, and has an excess charge
You need to learn the formulas, names, and charges of these very quickly. I recommend flash cards.
flash card? what is that?
