An electron has principal quantum number `3`. The number of its (i) sub-shell and (ii) orbitals would be respectively.

A

3 and 5

B

3 and 7

C

3 and 9

D

2 and 5

Text Solution

Verified by Experts

The correct Answer is:
C
The principle quantum number n = 3. Then azimuthal quantum number l has 3 values and number of orbitals = `n^(2)=3^(2)=9`. 3 and 9.
