The Reactivity Series
The Reactivity Series

Metals do not all react in the same way. Some take part in chemical reactions easily, while others barely react at all. A metal's reactivity is a measure of how easily it forms positive ions by losing electrons.
Step-by-step lessons on CIE IGCSE Chemistry Reactivity series. 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.
