Which of the following statements is/are correct?
(a) Transition elements exhibit higher enthalpies of atomization as they have stronger interatomic interaction.
(b) \( \mathrm{IE}_{2} \) of \( { }_{23} \mathrm{~V}{ }_{24} \mathrm{Cr}{ }_{25} \mathrm{Mn} \) and \( { }_{28} \mathrm{Ni}{ }_{29} \mathrm{Cu}{ }_{30} \mathrm{Zn} \).
(c) \( \mathrm{Ni} \) (II) compounds are more stable than \( \mathrm{Pt}(\mathrm{II}) \) where as Pt(IV) compounds are more stable than nickel (IV).
(d) The elements which give the greatest number of oxidation states do not occur in or near the middle of the series.
