Reactivity Series
Ranking the metals, and using the ranking to predict what will happen.
What this lesson covers
Reactivity Series is a 10-part Class 8 Science lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
The reactivity series lists metals in order of how readily they react. Potassium, sodium and calcium are at the top; copper, silver and gold are at the bottom. It is a genuinely predictive tool, not just a list to memorise.
