For the first row transition metals, the E^{-} values are E^{-} V Cr Mn Fe Co Ni Cu (M^{2+}/m) - 1.18 - 0.90 - 1.18 - 0.44 - 0.28 - 0.25 + 0.34 What is the reason for the non-regularity in the above values ?

Correct Answer is : non-regular variation of ionisation enthalpies

non-regular variation of ionisation enthalpies

different number of electrons present in M^{2+} ions

non-regular variation of ionic radii

the variation in densities of transition metals
