Hi, guys. Before end of class, there is the last thing I am going to introduce, please listen.
What is that?
What's that ??????
Anyone know ionization energy?
Ionization is the minimum amount of energy required to remove the most loosely valance electron to form a cation.
Based on what we just said, Ionization energy must have exceptions.
Yeah. But it is easier to determine.
The paired electrons in the 2p-orbital of oxygen are constantly repulsing against each other, increasing their energy and making it easier to remove an electron. Generally, groups 2 and 15 have a slightly higher ionization energy than groups 13 and 16 respectively because of these two concepts.
For example. The electron configuration of nitrogen is 2s2 2p3 and of oxygen is 2s2 2p4. Nitrogen has 3 unpaired electrons in the 2p-orbital while oxygen has 2 unpaired electrons and 1 paired electrons in the same orbital.
Wow, are you sure that is eaiser?
Yeah, See you Mr Science.
Actually correct. It is just seem longerbut eaiser to understand. Ok, you are dismissed.
