Question

The correct order of size of Ni,pd,pt

Answer 1

Explanation:

It is known that elements present in same group show increase in size of atom when we move down the group due to addition of electrons into new shells.

Hence, elements Ni, Pd and Pt are all transition elements and all of them belong to the same group as they lie in column 10.

So, they are placed from top to bottom in the order as Ni, Pd and then lies Pt.

Thus, we can conclude that correct order of increasing size is Ni < Pd < Pt.

Answer 2

Answer:

Ni<Pd<Pt

Explanation:

In a group, on moving down from top to bottom, the ionic radius increases.

Hence, Ni<Pd<Pt
