Answer 1

Answer:

the number of valence electrons of x is equal to six and the the valency of x is 8 - 6 that is 2

Answer 2

Answer:

no. of valence electrons = 6

Valency = 2

Explanation:

The element X is Oxygen so the electronic configuration of oxygen is 2,6 and 2 electrons are need to complete the shel so the valency of the element will 2
