Expert Answer:

The electronic configurations are:

1) Sn - 2, 8, 18, 18, 4

2) Pb -  2, 8, 18, 32, 18, 4

3) Fe - 2, 8, 14, 2

4) Ag  - 2, 8, 18, 18, 1

When an atom with electron orbital is full or half-full (or empty) is most stable.

The most stable 2+ oxidation state is shown by Lead (Pb) due to ‘inert pair effect’ phenomenon.
