Metal + Oxygen =
Metal Oxide
What is oxidation?
When a metal gains oxygen
What is reduction?
The loss of oxygen
What happens when metals react with other substances
Metal atoms form positive ions
What is the reactivity of a metal related to
Its tendency to form positive ions
Where is lithium in the reactivity series
Between sodium and calcium
What can a more reactive metal do?
displace a less reactive metal from a compound
How can metals be put in order of reactivity
By their reactions with water and dilute acids
Oxidation is the ….
Loss of electrons
Reduction is the …
Gain of electrons
How are most metals found?
As compounds that require chemical reactions to extract the metal
How can metals less reactive than carbon be extracted?
Reduction with carbon
How is gold found in the Earth? Explain why this is.
As the metal itself as it is very unreactive
