Vedclass · Answer

(A, C) The electronic configuration of Silicon $(_{14}Si)$ is $1s^2 2s^2 2p^6 3s^2 3p^2$. In the $3p$ subshell,there are two electrons in separate orbitals according to Hund's rule,resulting in $2$ unpaired electrons. Thus,option $A$ is correct.The electronic configuration of Phosphorus $(_{15}P)$ is $1s^2 2s^2 2p^6 3s^2 3p^3$. In the $3p$ subshell,there are three electrons in separate orbitals,resulting in $3$ unpaired electrons. Thus,option $C$ is correct.
