Hello, this question it is related to poly exclusion principle and here we are given these five orbitals with electrons filled in this case.
00:10
So here as we know that that is poly exclusion it states that that is no two electron or we can say in the same atom can have the identical values of four of their quantum numbers.
00:26
So here we have this no more than two electrons can occupy the same orbitals.
00:33
No, more than two electrons can occupy same orbital.
00:43
That means one orbital, it can have maximum two electrons.
00:48
And these two electrons in the same orbital, they must have opposite spins.
00:56
Opposite spins.
00:58
They should be present in this form here.
01:02
So here we just need to find out that orbital, that option, which is violating this polyexam.
01:08
Exclusion law.
01:09
So here we have this in this first case that is orbital it is filled here but in this case b orbital this pairing it is aggrubed.
01:18
So according to this hons rule, every orbital in a sub level it is singly occupied before any orbital is doubly occupied so it should be in this way...
