A Covalent Bond is a type of chemical bond formed when two atoms share one or more pairs of electrons to achieve a stable electronic configuration (usually the octet).

Definition

A covalent bond is a bond formed by the mutual sharing of electrons between two non-metal atoms.

Example

In Hydrogen molecule (Hβ‚‚), each hydrogen atom has 1 electron.

They share their electrons, forming one shared pair, which creates a single covalent bond.

Representation:
H β€’ + β€’ H β†’ H : H or H–H

Types of Covalent Bonds

1. Single covalent bond – one pair of electrons shared
Example: Hydrogen molecule (Hβ‚‚)

2. Double covalent bond – two pairs of electrons shared
Example: Oxygen molecule (Oβ‚‚)

3. Triple covalent bond – three pairs of electrons shared
Example: Nitrogen molecule (Nβ‚‚)

Characteristics of Covalent Compounds

Usually formed between non-metals

Low melting and boiling points

Poor conductors of electricity

Often exist as gases, liquids, or soft solids

Example Compounds
Water (Hβ‚‚O)
Methane (CHβ‚„)
Carbon dioxide (COβ‚‚)
