What is Ionic Bonding?

Ionic bonding is a type of chemical bonding formed through the transfer of electrons from one atom to another. It usually occurs between a metal and a non-metal.

When an atom loses electrons, it becomes a cation (+).
When an atom gains electrons, it becomes an anion (−).

Opposite charges attract — forming a strong ionic bond.

How Does Ionic Bonding Form?

Example: Sodium (Na) and Chlorine (Cl)

Sodium loses 1 electron → Na⁺
Chlorine gains 1 electron → Cl⁻
Electrostatic attraction forms NaCl

Properties of Ionic Compounds

High melting & boiling points
Conduct electricity when molten or dissolved
Usually soluble in water
Form crystal lattice structures

Real-Life Examples

Sodium chloride (table salt)
Magnesium oxide
Calcium fluoride
