Question

Among the following which elements have its lower oxidation state stable than their higher oxidation state-PbSnTlSb

-xA0-In group 13- the characteristic group oxidation state of -3 is known but the -1 state gets progressively stabilized on going down the group- It is particularly favored by Tl- This is a consequence of the so called -apos-inert pair effect-apos- which also accounts for the stability of the dipositive oxidation states of Sn and Pb and tripositive state of Bi-
