How many subshells are present in n=3 shell:
Correct answer: B. 3
- A. 4
- B. 3
- C. 5
- D. 9
Explanation
This option is correct. The n=3 shell has three subshells corresponding to l=0, l=1, and l=2. Therefore, the correct option is "3" as there are three subshells (s, p, and d) in the n=3 shell according to the allowed values of l.

About Quantum Numbers
Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
