- Metals react with many substances
- air
- water
- acid
- air
- Some metals are more reactive than others
- oxygen is the most reactive in air
- nitrogen is the least reactive in air
- oxygen is the most reactive in air
- the reaqctivity of metals is linked to their uses
- metals used for consturction has low reactivity
- metals used for consturction has low reactivity
- Many low reactivity metals have been known for hundreds of years
- More reactive metals are extracted by electrolysis meaning they only have been discovered in the last 200 years
- oxidised = when a subject reqacts with oxygen to form an oxide
- electrolysis
- acids
