Chemical Bonding: Ionic, Covalent and Metallic

Why atoms stick together, and how it shapes the properties of matter.

Last updated July 8, 2026

In this guide

  1. 1. Ionic bonds
  2. 2. Covalent bonds
  3. 3. Metallic bonds

1.Ionic bonds

Formed when electrons transfer between a metal and a non-metal, producing charged ions that attract each other.

2.Covalent bonds

Formed when non-metal atoms share electrons. Bonds can be single, double or triple depending on shared pairs.

3.Metallic bonds

A 'sea' of delocalized electrons holds metal atoms together, giving metals conductivity and malleability.
