NEET 2023 Phase 1 · ChemistryPrevious Year Question

The relation between $n_{m}$ ( $n_{m}$ = the number of permissible values of the magnetic quantum number $m$ ) for a given value of the azimuthal quantum number $l$ is:

Answer: (A) $n_{m} = 2 l + 1$ . \textbf{Answer:} (A) $n_{m} = 2 l + 1$ \textbf{Solution:} For a given azimuthal quantum number $l$ , the magnetic quantum number $m$ takes values from $- l$ to $+ l$ including $0$ , giving $(2 l + 1)$ permissible values.

A. $n_{m} = 2 l + 1$ ✓
B. $l = 2 n_{m} + 1$
C. $l = \frac{n _{m} - 1}{2}$
D. $l = n_{m} + 2$

Correct Answer

(A) $n_{m} = 2 l + 1$

Solution & Explanation

\textbf{Answer:} (A) $n_{m} = 2 l + 1$ \textbf{Solution:} For a given azimuthal quantum number $l$ , the magnetic quantum number $m$ takes values from $- l$ to $+ l$ including $0$ , giving $(2 l + 1)$ permissible values. Hence $n_{m} = 2 l + 1$ .
