Chemistry Paper 1
Reactivity series
Chemical Changes training before the targeted original question drill.
Adaptive teaching card
Make it concrete
Analogy
Reactivity series is like changing a recipe: the particles, amounts and conditions decide what product you can make.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
More reactive metals can displace less reactive metals from compounds.
Metals react with acids to produce salts and hydrogen.
Reduction is the loss of oxygen or gain of electrons.
