Question

State Pauli's Exclusion principle. Write electronic configuration of Mn (Z=25)

​

Answer 1

Answer:

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..

Mn (z=25) -> 1s2, 2s2 , 2p6, 3s2, 3p6, 4s2, 3d5.
