In this problem, we're looking at group 16 atoms.
00:06
So here, we want to know about valence electrons.
00:12
So remember that most atoms, we're assuming eight electrons or an octet in order to be stable.
00:26
So if we look at group 16, and you've group one and two, you have your transition metal, and then you have more groups over here.
00:49
So you can actually use this idea to figure out how many balanced electrons you're going to have.
00:58
So if we ignore transition metals, we have one, two here.
01:04
And as you go across, you can count.
01:08
And your numbers in red are actually going to tell you how many balanced electrons you have...
