NEET Chemistry Quantum Mechanical Model MCQ Question

Type: MCQ-diagram based-Easy-Class 11

Consider a diagram that represents an atom's electron distribution divided into shells, subshells, and orbitals. If the principal quantum number n is given as 3, which set of quantum numbers (l, ml) is NOT possible within this diagram?

Question diagram
A

l = 0, ml = 0

B

l = 1, ml = -2

C

l = 2, ml = 1

D

l = 1, ml = 0

Correct Answer

Option B

Detailed Explanation

For n = 3, the possible values of l are 0, 1, and 2. The magnetic quantum number ml must satisfy -l ≤ ml ≤ +l. Therefore, for l = 1, ml cannot be -2.
