Explanation:
The capacity of an atom of an element to form chemical bonds is known as valency of an element.
An atomic number of oxygen is 8 so its electronic configuration is 2, 6.
Valency of non-metal oxygen = 8 – the number of valence electrons in its atom
= 8 – 6
= 2
Atomic number of silicon is 14 so its electronic configuration is 2, 8, 4.
Valency of silicon =8 – number of valence electrons in its atom
=8 – 4
=4
hope it will help you
