Question

An atom is the smallest unit of matter.

• A. True
• B. False

Answer 1

Answer: (A)

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Most atoms contain all three of these types of subatomic particles-protons, neutrons and electrons. In the center of an atom, a tiny nucleus is present which contains protons and neutrons, and electrons orbit around the nucleus.

Hence, option $A$ is correct.
