The ionization energies of the elements of first transitoin series do notvary much with increasing atomic number. Explain why

The first ionisation energies of the elements of the transition series.

The first ionisation energies of the elements of the first transition series (TitoCu)

The first ionization energies of group 16 elements

The atomic number of elements of first transition series lie in the range of

Transition metals tend to be unreactive with increasing atomic numbers in a series. Why ?

Wxplain the following giving suitable reson. (a). Transitin metals of 3d-series doe not react readily with dilute acids to liberate hydrogen although they have high negative reduction potential values. Explain. (b). The atomic radii of the elements in a transition series do not vary much while they do vary in the case of s and p-block elements. Explain. (c). The second and third members in each group of the transition elements group of the transition elements have similar atomic radii. Explain.
