`C` and `Si` are always tetravelent , but Ge, Sn and Pb show divalency Gvie reason .

C and Si are always tetravalent but Ge, Sn , Pb show divalency . Why ?

Account for the following: C and Si show tetravalency in most of their compounds but Ge, Sn and Pb show bivalency.

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

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

Why does EN value remain constant in Si, Ge, Sn and Pb ?

Sn, C, and Si, Ge are all group XIV elements. Yet, Sn is a conductor, C is an insulator while Si and Ge are semiconductors why?

Sn, C, and Si, Ge are all group XIV elements. Yet, Sn is a conductor, C is an insulator while Si and Ge are semiconductors. Why?

From the compounds of group IV elements C, Si, Ge, Sn and Pb write an appropriate example for each of the following. A giant covalent oxide.
