Question

The number of orbitals with $n=5,m_1=+2$ is ______. (Round off to the Nearest Integer).

Answer 1

Answer: 3

For, $n=5$

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

If $\ell =0,m=0$

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

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

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

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

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