Why atoms share electrons

Covalent bonding usually happens between non-metal atoms. Instead of transferring electrons, the atoms share electrons so each can reach a full outer shell.

Step-by-step lessons covering CIE IGCSE Chemistry Simple molecules and covalent bonds for Core and Extended tier. Each lesson works through exam-style questions in Paper 1 and Paper 3 (Core) or Paper 2 and Paper 4 (Extended), plus Paper 5 or Paper 6 format. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
