Single Choice

Total number of orbitals associated with third shell will be ____.

A$$2$$
B$$4$$
C$$9$$
Correct Answer
D$$3$$

Solution

Total number of orbitals in $$n^{th}$$ shell=$$n^2$$

where $$n$$=shell/principal quantum number

$$\therefore$$ Total number of orbitals in third shell= $$3^2=9$$

So, these orbitals are one $$3s$$-orbital, three $$3p$$-orbitals and five $$3d$$-orbitals.

Thus, the correct option is $$C$$
