How many orbitals make the N-shell? What is the subshell wise distribution of orbitals in the N-shell?

Answer»

For N-shell principal quantum number n = 4

∴ Total number of orbitals in N-shell = n² = 4² = 16.

The total number of subshells in N-shell = n

= 4.

The four subshells with their azimuthal quantum numbers and the constituent number of orbitals are as shown below :

Azimuthal quantum number (l)	Symbol of subshell	Number of orbitals (2l + 1)
l = 0	s	(2 × 0) + 1 = 1
l = 1	p	(2 × 1) + 1 = 3
l = 2	d	(2 × 2) + 1 = 5
l = 3	f	(2 × 3) + 1 = 7
