Select the incorrect statement ?A. `._(7)N` has higher `1^(st)` ionization enthalpy than that of `._(8)O` atom.B. `._(12)Mg` has higher `1^(st)` ionization enthalpy than that of `._(13)Al` atom.C. `._(31)Ga` has higher `1^(st)` ionization enthalpy than that of `._(13)Al` atom.D. `._(16)S` has higher `1^(st)` ionization enthalpy than that of `._(8)O` atom.

Answer» Correct Answer - 4
Down the group, the size of atom increases and therefore, distance between valence shell electron and nucleus increase. Thus the removal of valence shell electron will require less energy.
