Bonding as electrostatic attraction

Bonding as electrostatic attraction

Comparison of ionic bonding between Na+ and Cl-, covalent bonding in H2, and metallic bonding with positive metal ions and delocalised electrons

A chemical bond is a strong electrostatic attraction that holds atoms or ions together. Bonded particles are usually at a lower energy than separated particles, which is why bonding happens.

Step-by-step lessons covering Edexcel A Level Chemistry Bonding for A Level Chemistry. Each lesson works through exam-style questions in Paper 1, Paper 2 and Paper 3 format. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
