Question

Consider two cases if d orbital having 7 electrons and other having 5 electrons in d subshell . Which system will be more stable and why?
​

Answer 1

Answer:

obviously 5 I thing . it will be more stable

Answer 2

A system of 7 electrons will be more stable because this atoms has to take 1 electron or it can also share electron but the system of 5 electrons not stable because it have to gain 2 electrons and it neither can be shared
