Hello, this question is asking us for the five basic electron geometries.
00:11
So an electron geometry comes from the arrangement of electron groups about a central atom.
00:21
So let's start off and see what happens when we have two electron groups.
00:28
So here's our central atom.
00:30
If we put two electron groups on it, we get linear, because they're going to arrange themselves as far away from each other as possible, according to the vsepr theory, which gives us a linear shape.
00:42
Let's go ahead and put three electron groups on our central atom.
00:47
When they arrange themselves as far away from each other as possible, we get trigonal planar.
00:56
Putting four electron groups on, now we get a tetrahedral.
01:10
Next, we'll take our central atom and we'll put five electron groups on it...
