Vedclass · Answer

(B) The first ionization energy of $3d$ transition elements generally increases across the period due to an increase in effective nuclear charge. Among the given elements ($Sc$,$Ti$,$V$,$Mn$),$Sc$ (atomic number $21$) is the first element in the $3d$ series. As we move from left to right across the $3d$ series,the effective nuclear charge increases,which leads to a stronger attraction between the nucleus and the valence electrons,thereby increasing the ionization energy. Therefore,$Sc$ has the lowest first ionization energy among the given options.
