Question

The combining capacity of an element is known as -----------------------

Answer 1

Valency:

• Valency is defined as the number of electrons an atom can donate or accept to attain noble gas electronic configuration.
• Valency is defined as the combining capacity of an element.

Example: Carbon

Elecronic configuration: 2, 4

So, a carbon atom requires four electrons to attain noble gas electronic configuration. So, the valency of carbon is 4.

Therefore the combining capacity of an element is known as Valency
