If nitrogen atoms had el,ectonic configuration is ? It would have energy lower than that of the nornal ground state configuration `1s^(2) 2s^(2) 2p^(3)` because the electrons would be clear to the nucleus yet `1s^(2)` is not oberved because it violates ?

Options

A. Heisenberg's uncertainty principal
B. Hand,'s rule
C. Pauill's exclusion principle
D. Bohr's postatate of stationary orbit

Explanation

According to pauli's exclasion principle an orbit cannot have more then two elkement and these two electron have apposite spin the unpaired have spin in the same direction .Hence (a) and (d) are correct
