Vedclass · Answer

(D) The first ionization enthalpy generally increases across a period from left to right due to an increase in effective nuclear charge. For the $3d$ series elements $(Ti, Mn, Ni, Zn)$,the general trend is $Ti $Ti$ $([Ar] 3d^2 4s^2)$ has the lowest ionization enthalpy,while $Zn$ $([Ar] 3d^{10} 4s^2)$ has the highest due to its stable,fully-filled $d$-orbital configuration.

The correct order of the first ionization enthalpies is:
