Question

Which of the following set of quantum numbers belong to highest energy?
a) n= 2. I= 1, m=0, s= +1/2
b) n= 3. I= 0, m=0, s= +1/2
Dc) n= 4.1= 0, m=1, s= +1/2
d) n= 4.1= 1, m=1, s=+1/2​

Answer 1

Answer:

The set of quantum numbers n=3,l=2,m=1,s=+

21represents 3d orbital. It represents the highest energy of an atom.

The orbital which has higher value of (n+l) has higher energy. Among the given orbitals, for the 3d orbital, (n+l)=(3+2)=5 is maximum. Hence, it has highest energy.
