Question

What is the valency of sulphur in $S{O}_2$?

• A. 2
• B. 1
• C. 3

Answer 1

The correct option is A 2

The valency of sulphur in $S{O}_2$ is 2. Valency is defined as the combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine with. In $S{O}_2$ compound, sulphur forms bond with 2 atoms of oxygen. Hence its valency is 2.
