Question
During the process of corrosion
- Atoms of a metal combine with atoms of a non-metal
- Atoms of a non-metal combine with atoms of a non-metal
- Atoms of a metal combine with atoms of another metal
- Atoms of a metal combine with atoms of the same metal
Hint:
Metals react with elements in air leading to corrosion.
The correct answer is: Atoms of a metal combine with atoms of a non-metal
- Oxygen and other non metallic elements present in the air react with metal.
- These form compounds leading to corrosion.
