Question

discuss (n+1) rule for 2p and 3s orbitals​

Answer 1

Explanation:

This (n+l) rule is related to afbau principle and is one of the basic fundamentals of quantum theory.

according to this rule,

the orbitals or precisely subshells having higher (n+l) rule will have higher energy. If (n+l) value is same for two subshells then the one having higher n value will have greater energy.

in the question given,

2p orbitals : n = 2 , l = 1

(n+l) value: (2+1) = 3

3s orbital : n = 3 , l = 0

(n+l) value: (3+0) = 3

both 2p and 3s orbitals have same (n+l) value. But 3s orbital have a higher value of n than 2p orbitals.

So, 3s orbital will have a greater energy as compared to 2p orbitals.
