Explanation:
Detailed explanation-1: -The smallest atom? If by “biggest” and “smallest", you mean mass (which is a measure of how much matter is there), then the smallest is the hydrogen atom with one proton and one electron.
Detailed explanation-2: -Quark (noun, “KWARK”) Subatomic means “smaller than an atom.” Atoms are made up of protons, neutrons and electrons. Protons and neutrons are made of even smaller particles called quarks. Based on the evidence available today, physicists think that quarks are elementary particles.
Detailed explanation-3: -Atom Composition Particles that are smaller than the atom are called subatomic particles. The three main subatomic particles that form an atom are protons, neutrons, and electrons.
