Vedclass · Answer

(B) The atomic number of $Na$ is $11$. The electronic configuration of $Na$ is $1s^2 2s^2 2p^6 3s^1$. The valence electron is the one in the $3s$ orbital. For the $3s$ orbital: Principal quantum number $(n)$ = $3$. Azimuthal quantum number $(l)$ for $s$-orbital = $0$. Magnetic quantum number $(m)$ = $0$. Spin quantum number $(s)$ = $+1/2$ or $-1/2$. Thus,the correct set is $(n = 3, l = 0, m = 0, s = 1/2)$.

Which set of quantum numbers is correct for the valence electron of $Na$?
