The orbital diagram in which both the Pauli’s exclusion principle and Hund’s rule are violated is:
Open in App
Solution
The correct option is A
Pauli Exclusion Principle:
The Pauli Exclusion Principle states that, in an atom or molecule, no two electrons can have the same four electronic quantum numbers. As an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.
According to Hund's rule:
All orbitals will be singly occupied before any is doubly occupied
