Let's start this question with the definition of an ionic compound.
00:06
So an ionic compound is composed of a metal ion and a non -metal ion.
00:22
So let's look at what we have here.
00:25
First one here is fluorine and rubidium.
00:34
Rubidium is a metal.
00:35
Fluorine is a non -metal.
00:38
So forms an ionic compound.
00:40
That's a yes.
00:42
This would be f -minus, rubidium plus.
00:45
So the empirical formula here would be r -b -f.
00:48
Name here is ribidium fluoride.
00:53
Next we've got fluorine and barium.
01:00
Barium is a metal.
01:01
Fluorine is a non -metal.
01:02
So this is a yes.
01:03
Fluorine is f -minus...
