lolz... just noe poly as in many and atomic as in atoms... when a molecule contains more than one atom, it becomes a polyatomic molecule... u haf biatomic, triatomic etc etc...

so yea, basically, molecular covalent compounds are almost all polyatomic.... (i fink~~~)

Hmm

I would say:

Nitrate, Sulphate, Phosphate, Carbonate, Acetate (ethanoate), Permanganate, Ammonium, Hydroxide, Hydroxonium(or hydronium as they call it here) should be enough

I would add some 'hydrogen' containing polyatomic ions, such as hydrogencarbonate, hydrogensulfate, hydrogenphosphate, dihydrogenphosphate
