Question

Why stability of -2 Oxidation state decreases down the group in Group 16
elements?

Answer 1

Answer:

We know that-stability of higher oxidation state increases downwards in a group of transition series. But i think that the stability of lower oxidation should increase downwards due to lanthanide contraction. ... As we move down the group, size of atom increases and so ionisation energy decreases.
