The term "subatomic particle" is largely a retronym of the 1960s, used to distinguish a large number of baryons and mesons (which comprise hadrons) from particles that are now thought to be truly elementary. Before that hadrons were usually classified as "elementary" because their composition was unknown. A list of important discoveries follows:

A subatomic particle is a particle smaller than an atom. Subcategories. This category has the following 8 subcategories, out of 8 total. B. Bosons (5 C, 37 P) E.
In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons .
In particle physics, a boson (/ ˈ b oʊ z ɒ n / [1] / ˈ b oʊ s ɒ n / [2]) is a subatomic particle whose spin quantum number has an integer value (0, 1, 2, ...). Bosons form one of the two fundamental classes of subatomic particle, the other being fermions, which have odd half-integer spin (1 ⁄ 2, 3 ⁄ 2, 5 ⁄ 2, ...). Every observed ...
This list is of all known and predicted scalar, pseudoscalar and vector mesons. See list of particles for a more detailed list of particles found in particle physics. This article contains a list of mesons, unstable subatomic particles composed of one quark and one antiquark. They are part of the hadron particle

In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. [ 1 ] [ 2 ] They vary greatly in size or quantity, from subatomic particles like the electron , to microscopic particles like atoms and molecules ...
