Syllabus ref: 9.1

Reactivity means how easily substances undergo chemical reaction, and 'relative' means when compared to another substance.

In chapter 9.3, the concept of 'relative reactivity'; the chemical behaviour when compared with other similar substances is discussed.


The activity series ranks metals according to the ease with which they undergo oxidation.

Applications and skills

Deduction of the feasibility of a redox reaction from the activity series or reaction data.

In Chapter 9.3
