Vedclass · Answer

(C) The electronic configuration of Argon ($Ar$,$Z=18$) is $1s^2 2s^2 2p^6 3s^2 3p^6$.For a $p$-orbital,the magnetic quantum number $m$ takes values $-1, 0, +1$.In the $2p^6$ subshell,there are $3$ orbitals $(2p_x, 2p_y, 2p_z)$. Each orbital contains $2$ electrons.The orbital with $m = +1$ contains $2$ electrons.Similarly,in the $3p^6$ subshell,there are $3$ orbitals. The orbital with $m = +1$ contains $2$ electrons.Total number of electrons with $m = +1$ is $2 + 2 = 4$.

Consider the Argon atom. For how many electrons does this atom have $m = 1$?
