As learnt in

Azimuthal Quantum Number(l) -

For a given value of n, l can have n values ranging from 0 to n – 1, that is, for a given value of n, the possible value of l are : l = 0, 1, 2, ....( n –1)

-

 

 \therefore for n = 4, l = 0, 1, 2, 3

\therefore we have s, p, d & f orbitals

Total orbitals = 1+3+5+7

                    = 16


Option 1)

8

Option 2)

16

This solution is correct

Option 3)
