1. n_m = l + 2 2. l = n_m - 1/2 3. l = 2n_m + 1 4. n_m = 2l² + 1

The relation between n_m, (n_m = the number of permissible values of magnetic quantum number (m)) for a given value of azimuthal quantum number (l), is

1. \(n_m = l + 2\)

2. \(l = \dfrac{n_m - 1}{2}\)

3. \(l = 2n_m + 1\)

4. \(n_m = 2l^2 + 1\)

Best answer

Answer: 2. \(l = \dfrac{n_m - 1}{2}\)

Key idea: For a given \(l\), m takes values from \(-l\) to \(+l\) including 0.

Number of values: \(n_m = 2l + 1\). Rearranging, \(l = \frac{n_m - 1}{2}\). Option 2.
