Answer:
Air is a mixture.
- Element – It is a one single atom, it cannot be divided further.
Example: Calcium, phophorous
- Compound – ‘two or more different atoms’ chemically bonded together.
Example: water, ammonia
- Molecule - two or more different or same atoms ‘chemically bonded together’.
Example: Methane
- Mixture – Contains more than ‘one compound or elements’
Example: Chocolate milk, salt water.
‘Air is a mixture’ because it composed of several elements, gases and compounds.
