The smallest particle of any element is an atom, which consists of protons, neutrons, and electrons. These subatomic particles are the building blocks of matter and cannot be further broken down into smaller components without losing the fundamental properties of the element.
With a mass of about 9.10938215×10−31 kg. (0.510998910 MeV), electrons are not known to be formed of anything smaller than themselves. They are thus, elementary particles.
