Question

the electronic configuration of nitrogen is 1s2 2s2 2px1 2py1 2pz1 and not 1s2 2s2 2px2 2py1.why?

Answer 1

p orbitals are of same energy so they should be given electrons equally at first and they are given again in the order according to the availability of electrons

Answer 2

Answer:

the correct electronic configuration is 1sw 2s2 2px1 2py1 2pz1

Explanation:

the hunds rule supports this

because according to hunds rule the electron pairing in orbitals or will its starts the same energy are singly occupied

after this pairing of electrons starts with opposite spins
