Hi there.
00:03
In this question, we want to draw the lewis structure of so3, making sure that each of these atoms follows the octet rule.
00:12
So to do that, we need to determine how many valence electrons we have to work with.
00:16
Sulfur is in group 6a of the periodic table, so it has six valence electrons.
00:21
There are three oxygen atoms, and oxygen is also in group 6a, so each oxygen also has six valence electrons.
00:29
Adding 6 plus 18 gives us 24 valence electrons.
00:39
And since phalance electrons are represented as dots in a lewis structure, that gives us 24 dots.
00:48
Okay, let's go ahead and draw this lewis structure.
00:50
Sulfur is going to be in the middle, and it's going to be surrounded on three sides by oxygen atoms.
01:01
We know that there needs to be at least a single bond.
01:06
Between each oxygen and the sulfur to hold them together.
01:11
So that takes six of our 24 dots.
01:14
We have 18 dots remaining.
01:16
So let's go ahead and start completing those octets.
01:26
All right, at this point, i have used up all of my dots, but sulfur does not have an octet yet...
