Answer 2

Answer:

Atom is the smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has characteristic properties of a chemical element. As such atom is the basic building block of chemistry.

Or in simple words, atom is the smallest particle of a chemical element that can exist.

The Greek root of atom is atomos, which means "indivisible" because at that time electrons, protons and neutrons are not discovered.
