Chromium $[Z=24]$

Vedclass · Answer

(A) . Chromium $(Z=24)$: Electronic configuration $(EC) = [Ar] 3d^5 4s^1$. Number of unpaired electrons $= 6$.$B$. Iron $(Z=26)$: $EC = [Ar] 3d^6 4s^2$. Number of unpaired electrons $= 4$.$C$. Manganese $(Z=25)$: $EC = [Ar] 3d^5 4s^2$. Number of unpaired electrons $= 5$.$D$. Vanadium $(Z=23)$: $EC = [Ar] 3d^3 4s^2$. Number of unpaired electrons $= 3$.Therefore,chromium $(Cr)$ has the maximum number of unpaired electrons.
