The angular momentum of electron in the shell in which the g-subshell first appears is `x xx(h)/(2pi)`. The value of x will be:

Answer

5

Explanation

`l=4` for subshell
Thus, the subshell will first appear in `(n=l+1=5)` 5th shell. ltbr. Angular momentum `(mvr)=n(h)/(2pi)`=5(h)/(2pi)`
`thereforen=5`
