Question

define the valency taking example of silicon and oxygen
​

Answer 1

Answer:

The valency of an element is the combining capacity of that element. For example, the atom of oxygen has six valence electrons. ... Thus, the valency of oxygen is (8 ˆ' 6) i.e., two

Answer 2

The valency of an element is the combining capacity of that element. The valency is determined by the number of valence electrons present in the atom of that element. Thus, the valency of silicon is four.
