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?

Answer»

non regular variation of ionization enthalpies
different NUMBER of electrons present in `M^(2+)` ions
non-regular variation of ionic radii
the variation in DENSITIES of transition metals.

Solution :A it is the CORRECT reason. For DETAILS CONSULT section 8:4
