1.	On the basis of Pauli's exclusion principle show that the maximum number of electrons in the M-Shell (n = 3) of any individual atom is 18.
Answer» According to Pauli's exclusion principle, "only two electrons may exist in the same orbital and these electrons must have opposite spin." For M-shell n = 3 Maximum number of electrons in the shell = 2n² = 2(3)² = 18

Answer»

According to Pauli's exclusion principle, "only two electrons may exist in the same orbital and these electrons must have opposite spin."

For M-shell n = 3

Maximum number of electrons in the shell

= 2n²

= 2(3)²

= 18
