Question

Which of the following set of quantum numbers are NOT allowed?
n =5 , ℓ =3 , mℓ =-2 and ms =+1/2 n =5 , ℓ =5 , mℓ =3 and ms =+1/2 n =5 , ℓ =4 , mℓ =3 and ms =+1/2 n =3 , ℓ =2 , mℓ =-3 and ms =-1/2

Answer 1

Answer:

n=5 l=5 ml=3 Ms=+1/2

n and l values can't be same according to Pauli's exclusive principle.
