So friendly remember, friendly reminder, ionic forms with a metal and a non -metal.
00:08
Covalent forms with two non -metals.
00:14
And metallic forms with metal.
00:19
So we're asked which will form ionic compounds.
00:23
So we have a, which has lithium and chloride.
00:27
Well, lithium is a metal, and chlorine is a non -metal.
00:30
Therefore, this is most likely going to be ionic.
00:33
Then we have oxygen and bromine, which are two non -metals.
00:39
Therefore, this would most likely be a covalent bond and not ionic, excuse me.
00:46
Part c is potassium and oxygen.
00:48
Potassium is a metal, an oxygen is a non -metal.
00:53
Therefore, this would be ionic.
00:56
Part d is sodium and neon, so n -a and n -e.
01:01
Now remember how i said it's a metal and a non -metal...
