Question

what is covalency? with an example

Answer 1

Explanation:

Covalency, it is a combining capacity of central atom with its surrounding atoms.

Example: Sulphuric acid (H2SO4)

Oxygen atom is more electronegative in nature as compare to sulphur atom. So covalency of sulphur in sulphuric acid is +6 as it forms two double co-valent bonds and two single covalent bonds with oxygen atoms.
