Question

Define valence explain by taking exampleof siliconand oxygen
l

Answer 1

Valency is number of electrons in valence shells

In silicon electronic configuration 2,8,4 valency is 4 and in oxygen 2,6 it is 2 because if number of electons increase by 4 then valency is 8-number of electrons

Answer 2

In chemistry, the valence or valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules.
