Which rule is violated in the electronic configuration `1s^(0) 2 s^(2) 2p^(4)` ?

Text Solution

Verified by Experts

1) Aufbau principle is violated in this electronic configuration because according to Aufbau principle, electron enters orbital of lowest energy.
2) Among 1 s, 2s and 2p, 1 s has least energy.
3) So 1 s orbital must be ftlled before the electron should enters 2s.
