Question

What would be the full electron configuration of the calcium atom if there were no pauli exclusion principle?

Answer 1

$1 {s}^{2} 2 {s}^{2}2 {p}^{6}3 {s}^{2} 3 {p}^{6} 4 {s}^{2}$
in normal electronic configuration method
$in \: n {l}^{x} method$

the electronic configuration of calcium if we apply pauli's exclusion principle is same if we do not apply pauli's exclusion principle but the actual difference can be shown in orbital electronic configuration method.
