Question

The valency of ammonium and carbonate radicals is …… and ….. respectively. *​

Answer 1

The valency of ammonium and carbonate radicals is +1 and -2 respectively.

• Valency refers to the tendency of an element to lose or gain electrons in order to attain a stable electronic configuration.
• Ammonium ion (NH₄⁺) is formed when ammonia is protonated. And it has a valency of 1.
• On the other hand, carbonate ion refers to the formula CO₃²⁻. Clearly, it has a valency of 2.
