Question

According to the n + l rule after np level is filled with electron the next electron will enter into

Answer 1

Explanation:

If there are two orbitals that have the same value of (n+l) then the orbital that has the least value of 'n' will be filled first. EXAMPLE # 01: 2p-orbital will be filled prior to 3s-orbital. COMMENTS: Since 2p-orbital has least value of n, therefore, it will occupy electrons before 3s-orbital.
