Q. The number of orbitals with $n = 5, m_{1} = + 2$ is ______. (Round off to the Nearest Integer).

JEE MainJEE Main 2021Structure of Atom

Solution:

For, $n =5$

$\ell=(0,1,2,3,4)$

If $\ell=0, m =0$

$\ell=1, m =\{-1,0,+1\}$

$\ell=2, m =\{-2,-1,0,+1,+ 2 \}$

$\ell=3, m =\{-3,-2,-1,0,+1,+2,+3\}$

$\ell=4, m =\{-4,-3,-2,-1,0,+1,+2,+3,+4\}$

$5 d , 5 f$ and $5 g$ subshell contain one-one orbital having $m _{\ell}=+2$
