Question
Metal reacts with the oxygen in the air to give their respective metal ______?
- Carbides
- Oxides
- Nitrides
- Phosphates
Hint:
Reaction of metal with oxygen gives metal oxide.
The correct answer is: Oxides
Metals react with atmospheric oxygen and produce metal oxide which are basic in nature, and that is because metals also react with water to form bases.
Metal + oxygen 
metal oxide
Mg + O2 MgO
Rusting is outcome of forming metal oxide layer over metal.
