All right, guys.

Problem 6, chapter 7.
00:02
Explain what a graph of ionization energy versus atomic number across the row is not linear.
00:08
And they wonder, where are the exceptions and why are their exceptions? so this is a basic graph of atomic ionization energy across a row.
00:19
So you're going to see a steadily increase energy in ionization energy across a row.
00:32
That's because as you go across the row, you're adding more protons to your nucleus.
00:39
The core number of electrons in your core shell stay the same.
00:47
So that's going to increase your effective nuclear charge because remember, effective nuclear charge is your nuclear charge minus minus the number of core electrons.
01:01
And the number of core electrons are going to be stayed the same in this case.
01:04
So you're going to see an increase as you go from one valance electron to two valance electrons.
01:09
And i'm just using 2s, 2p, and 6am.
01:11
This works for 3s, 3p, 4s, 4p, etc.
01:14
So now, you'll notice you see a drop in when you hit the third one in the row.
01:19
That's because you're adding an electron to the 2p orbital.
01:24
So you're going from a low energy orbital like 2s to a higher energy orbital like 2p...
