The stability of ions of Ge Sn and `Pb` will be in the order .

Stability of ions of Ge Sn and Pb will be in the order (1) Ge^(2+) lt Sn^(2+) lt Pb^(2+) (2) Ge^(4+) gt Sn^(4+) gt Pb^(4+) (3) Sn^(4+) gt Sn^(2+) (4) Pb^(2+) gt Pb^(4+)

The stability of dihalides of Si,Ge, Sn and Pb follows the sequence.

The stability of dihalides of Si,Ge, Sn and Pb increases steadily in the sequence :
