Untrue PSI From Lecture

Postby Trent Yamamoto 2J » Wed Oct 16, 2019 10:25 pm

At the end of today's lecture, Lavelle wrote some PSI values on the board and said that they were untrue. One of them was PSI (1, 1, 0, +1/2); can someone explain why this wouldn't be able to exist?

This is because the first 1 is referring to the number of electron shells, which correlates to the first row of the periodic table. The second 1 is referring to a p-orbital. This could not exist since none of the elements with only 1 electron shell can contain a p-orbital.

In the first energy level, n=1, the only possible orbital that can be found is an s orbital with l=0 because there are only 2 electrons in available to fill the first energy level.
