Hello Aspirant

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. ... The term " atom " comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided.

Hope it helps

Thank you & Good Luck!!!
