Question

which combination of quantum number n,l,m and s for the electron in an atom does not provide a permissible solution of the wave equation
(1) 3,2,-2,1/2. (2) 3,3,1,-1/2
(3) 3,2,1,1/2 (4) 3,1,1,-1/2

Answer 1

The second option (b) does not give a permissible wave configuration. This is because -

Here the value of n and l both are given as 3.

This can not happen because the max value of 'l' that an atom can have is n-1.

Here n=3 which means the value of n can not exceed 2
