Answer 2

Answer:

The correct option is (d) All of these.

Explanation:

• A pure substance is made up of one type of atom. This kind of substance is called an element. The chemical nature of each of these atoms has to be the same.
• Example- Atoms of pure gold. Gold is said to be pure if does not contain atoms of any other element otherwise it will become impure and will be called a compound. The impurities will alter the chemical properties of the gold.
• Many things are made up of more than one type of atom. Example- Water. It is made up of one oxygen atom and two hydrogen atoms.
