Answer 1

hey dear here is your answer

as the Atomic number increases atomic size
gradually decrease due to poor screening effect of F orbitals


consequences :-

1) due to Lanthanoid contraction
4d, 5d series elements are similar in size.


2) the separation of Lanthanoid elements is very difficult due to similar size and similar structure.

3) due to Lanthanoid contraction inner pair effect arise


hope helps you
