Let us take $d^6$ orbital as an example:
A) ↑ | ↑ | ↑ ↓ | ↑ | ↑ |
Now , this one 1 way. My Q is that how is it possible that in the 3rd box , we have a paired electron but not in the 1st one. Like it should pair in a series right ? From 1st , 2nd & then 3rd one.
B) We know ↑ ↓ | ↑ | ↑ | ↑ | ↑ |
This one I know is correct as all the examples in my textbook are written in this order but in a Q , Option A is also correct.
I want to know why & how ?
