(C) The atomic number of Chromium $(Cr)$ is $24$.Its expected electronic configuration is $[Ar] 3d^4 4s^2$.However,due to the extra stability of half-filled $d$-orbitals,the actual electronic configuration is $[Ar] 3d^5 4s^1$.In this configuration,there are $5$ unpaired electrons in the $3d$ subshell and $1$ unpaired electron in the $4s$ subshell.Therefore,the total number of unpaired electrons is $5 + 1 = 6$.

What is the total number of unpaired electrons present in the observed electronic configuration of $Cr$ $(Z=24)$?
