Question

a) Describe the following character of 1st transition series (Sc to Zn)
(i) Atomic radii
(ii) Oxidation radii
(iii) Ionisation enthalpy
​

Answer 1

1) atomic radii decreases as nuclear charge increases from left to right

2) oxidation radii increases up to Fe and then starts decreasing up to Zn

3) ionization energy increases from left to right but it is maximum for half filled and completely fill orbitals i.e. Mn and Zn have the highest ionization energy ..

Hope these answers will help you dear❤️❤️
