Question

Which of the following is the simplest form of matter?

• A. Element
• B. Mixture
• C. Compound
• D. None of these

Answer 1

The correct option is A

Element

Correct Answer: Option(A)-Element

The Explanation for the correct answer:

1. Matter: The substance which occupies space and has a mass that can be felt by our five senses.
2. Element: The pure substance only contains one type of atom.
3. An Element is the simplest form of matter which cannot be changed further by chemical or physical methods. They are the basic unit of the matter.
4. Example:${\mathrm{O}}_2,{\mathrm{H}}_2,{\mathrm{N}}_2$.

The Explanation for the incorrect answer:

Option(B)-Mixture:

1. A material that contains more than one type of substance and which is mixed in any ratio by weight.
2. The property of the mixture is the property of its components.
3. Examples:$\mathrm{Sugar}+\mathrm{water},\mathrm{Sand}+\mathrm{water}$.

Option(C)-Compound:

1. A substance that contains more than one type of atom or element.
2. The properties of the compound are completely different from those of its constituent elements.
3. Examples:$\mathrm{water}\left({\mathrm{H}}_2\mathrm{O}\right),\mathrm{Carbon}\mathrm{dioxide}\left({\mathrm{CO}}_2\right)$.

Therefore, the simplest form of matter is element-option (A).
