MCQ (Single Correct Answer)

-1

The relation between $$\mathrm{n}_{\mathrm{m}},\left(\mathrm{n}_{\mathrm{m}}=\right.$$ the number of permissible values of magnetic quantum number $$(\mathrm{m})$$) for a given value of azimuthal quantum number $$(l)$$, is

$$l=2 \mathrm{n}_{\mathrm{m}}+1$$

$$\mathrm{n}_{\mathrm{m}}=2 l^{2}+1$$

$$\mathrm{n}_{\mathrm{m}}=l+2$$

$$l=\frac{\mathrm{n}_{\mathrm{m}}-1}{2}$$
