I recently learnt electronic configurations. Also, I learned about exceptions of Chromium and copper of exchange energy concept i.e. violation of aubau's principle.
My question is : Electronic configuration of carbon:
1s^2 2s^2 2p^2. Why can't carbon do this by filling an orbital in p subshell from s??. Why? Please answer.
Dear student,
This is in accordance with Hund's Rule which states that every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
This rule cannot be violated in any case. So it is not possible for these two electron to occupy same orbital.
