Hi there, in this question we have some polyatomic ions.
00:11
And a polyatomic ion is the name we use for two or more atoms that are covalently bonded, but as a group have a charge.
00:40
Okay, so a lot of these formulas and names for polyatomic ions, we really just have to be memorized.
00:48
However, within a series there is a pattern.
00:51
So what i mean by that is let's look at the series that we can make with chlorine and oxygen.
00:59
We have clo with a negative charge, there's clo2 with a negative charge, there's clo3 with a negative charge, and there's clo4 with a negative charge.
01:14
So this is a series within these polyatomic ions where they just have a differing number of oxygens.
01:21
Well, the one that has the fewest oxygen of the four is known as the hypo with a suffix of i -t -e.
01:32
So it's the hypo chloride ion...
