Lithium, sodium and potassium are the main Group 1 elements you study. They are called alkali metals because they react with water to form soluble hydroxides, so the solution becomes alkaline.

Step-by-step lessons on Edexcel IGCSE Chemistry Group 1 (alkali metals) – lithium, sodium and potassium. Each one builds up to exam-style questions. 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.
