Question: 1 / 400

What is the smallest representative unit in chemistry?

Atom

Atoms are the smallest representative unit in chemistry, as they are the basic building blocks of matter. A molecule is made up of two or more atoms bonded together, so it is not the smallest unit. An ion is an atom or molecule that has gained or lost electrons, making it electrically charged, so it is also not the smallest unit. A proton is a subatomic particle found in the nucleus of an atom, but it is only one component of an atom and not the entire unit itself. Therefore, the correct answer is A Atom.
