Zeeman effect
Pauli's exclusion principle
Stark effect
Heisenberg principle
Solution
Pauli's exclusion principle is, "No two electrons in an atom can have the same set of all four quantum numbers".
e.g. for \(4 s^2\) configuration, its
\(\begin{aligned} & \text { 1st } e^{-}=\begin{array}{lllc}n & \boldsymbol{l} & \boldsymbol{m} & \boldsymbol{s} \\ & 0 & 0 & +1 / 2\end{array} \\ & \text { 2nd } e^{-}=4 \quad 0 \quad 0 \quad 0 \quad-1 / 2 \\ & \end{aligned}\)
