Read the following statements and choose the incorrect statement.
(1) The first ionization enthalpy of the d-block element in a given period is greater than those of the preceding s-block element.
(2) The variation in the first ionization enthalpy is quite small in the first transition series.
(3) The filling of the \( 5 \mathrm{f} \) orbital before the \( 5 \mathrm{~d} \) orbital results in a regular decrease in the atomic radii called lanthanoid contraction.
(4) \( \mathrm{Zr} \) and \( \mathrm{Hf} \) have similar atomic radii due to lanthanoid contraction.
