The reactivity series · ⁨活泼性顺序⁩

Ranking the metals

• Some metals react violently; others barely react at all.
• The reactivity series 金属活动性顺序 ranks metals from most to least reactive.

The reactivity series

• Metals are listed from most reactive (potassium) to least reactive (gold).
• The order: potassium, sodium, calcium, magnesium, zinc, iron, copper, gold (and more).

The reactivity series ranks metals from most reactive at the top to least reactive at the bottom.

Displacement reactions

• A more reactive metal will displace 置换 a less reactive one from its compound.
• For example, iron displaces copper from copper sulfate solution.

Reactions with water and acid

• The most reactive metals react with cold water; less reactive ones only with acid; the least don't react.
• The series predicts how vigorously a metal will react.
