Vedclass · Answer

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