Question

The angular momentum of an electron in the shell in which the $g$-subshell first appears is $x\times \frac{h}{2\pi }$. The value of $x$ will be:

Answer 1

$l=4$ for $g$-subshell.
Thus, the subshell will first appear in $(n=l+1=5)$ $5$th shell.
Angular momentum $\left(mvr\right)=h\frac{h}{2\pi }=5\frac{h}{2\pi }$
$\therefore$ $n=5$.
