Hi there, in this question we are trying to name this, which can be challenging if we can't recognize polyatomic ions when we see them.
00:12
So there is a certain amount of memorization that needs to go into recognizing these polyatomic ions, because what a polyatomic ion is, is it's two or more atoms covalently bonded that as a unit, they have a charge.
00:54
Okay, so as we're looking at this, if we're familiar with these, we recognize the nh4, and there are two of those, because each one has a positive one charge.

We recognize that as the ammonium ion.
01:11
So that is the polyatomic ammonium ion.

And we recognize co3, it has a two negative charge, as the polyatomic ion known as carbonate...
