the number of valence electrons of the atom of an element is less than or equal to four, then the valency of that element is equal to the number of valence electrons. For example, the atom of silicon has four valence electrons. Thus, the valency of silicon is four. ... Thus, the valency of oxygen is 8
The valency of an element is the combining capacity of thatelement.The valency of an element is determined by thenumber of valence electronspresent in the atom of thatelement.
If the number of valence electronsof the atom of an element is lessthan or equal to four,then the valency of that element isequal to the number of valence electrons.
For example,the atom of silicon has four valence electrons.Thus,the valencyof silicon is four.
On the other hand,if the numberof valence electrons of the atom ofan element is greater than four,then the valency of that element is obtained by subtracting thenumber of valence electrons fromeight.
For example,the atom of oxygen has six valence electrons.

Explanation:
The valency of an element is the combining capacity of that element. The valency of an element is determined by the number of valence electrons present in the atom of that element.
If the number of valence electrons of the atom of an element is less than or equal to four, then the valency of that element is equal to the number of valence electrons.
For example, the atom of silicon has four valence electrons. Thus, the valency of silicon is four.
On the other hand, if the number of valence electrons of the atom of an element is greater than four, then the valency of that element is obtained by subtracting the number of valence electrons from eight.
For example, the atom of oxygen has six valence electrons.
Thus, the valency of Oxygen is (8 – 6) i.e., two.
