To determine whether substances are ionic or molecular, the easiest way to do that is determine if there's a metal in this system.
00:13
So if there is a metal and a non -metal, that is going to wind up being ionic.
00:24
You're going to get the two substances together because they're ions, positive and negative, come together.
00:30
But if you have a non -metal with another non -metal, that is going to wind up being a molecular compound.
00:42
We get molecules instead of ions.
00:45
So if you're looking at something like co2, both of these are non -metals.
00:52
And how can you check whether something's a metal or not? if you go over to the periodic table, what you should see on a standard table is a little staircase.
01:03
On the right hand side, which separates the metals from the non -metals.
01:10
So you can check where the element is.
01:13
In co2, they're both non -metals.
01:15
So that's going to wind up being molecular...
