Question

the electronic configuration of Nitrogen is written as 1s²2s²2px¹2py¹2pz¹ and not as 1s²2s²2px²2py¹. Explain​

Answer 1

Answer:

if an element's orbitals are half filled or full filled it attains more stability so nitrogen configuration is written like that

Answer 2

This is because by Hunds rule , every orbital in a sub level is singly occupied before any orbital is doubly occupied . So electrons fill all orbitals with similar energy before pairing with another electrons in half filled orbitals.

Electrons are negatively charged and electrons repel each other. So they tend to minimize repulsion by occupying their own orbitals .
