JEE Main 2024 — 4 April, Shift 2 — Question 76

The maximum number of orbitals which can be identified with $\mathrm{n}=4$ and $\mathrm{m}_{l}=0$ is $\_\_\_\_\_$ .

Answer: 4

Numerical answer — enter this value.

For $n=4$ , allowed values of $\ell$ are $\ell=0,1,2,3$

For each subshell, the magnetic quantum number $m_\ell$ ranges from $-\ell$ to $+\ell$ .

Each subshell contains exactly one orbital with $m_\ell=0$ .

Thus, total orbitals $= 1+1+1+1=4$
