- Reactivity
- Reactivity series
- Metals are in order of reactivity towards other substances
- When metals react with water/acid they lose electrons and form positive ions
- Acid + metal = salt + hydrogen
- More reactive a metal is, the faster the reaction will go
- Potassium, sodium and lithium react explosively. Magnesium, zinc and iron react less violently
- Copper won't react with cold, dilute acids
- Metal + water = metal hydroxide + hydrogen
- Potassium, lithium and sodium react with water
- Zinc, copper and iron won't react with water
- Reactivity series
