Vedclass · Answer

(D) The first ionization potential generally increases across a period from left to right due to an increase in effective nuclear charge.For the $3d$ series elements,the electronic configurations are:$Ti (Z=22): [Ar] 3d^2 4s^2$$V (Z=23): [Ar] 3d^3 4s^2$$Cr (Z=24): [Ar] 3d^5 4s^1$$Mn (Z=25): [Ar] 3d^5 4s^2$Among these,$Mn$ has a stable half-filled $d$-subshell $(3d^5)$ and a completely filled $s$-subshell $(4s^2)$,which makes it more difficult to remove an electron compared to the others.Therefore,$Mn$ has the highest first ionization potential.

Which of the following elements has the maximum first ionization potential?
