Neutronium, hypothetical nuclei consisting only of neutrons (more than one). Examples include the tetraneutron. Preons were suggested as subparticles of quarks and leptons, but modern collider experiments have all but ruled out their existence. Rishons, particles from the Rishon model of preons. From superseded and obsolete theories
Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. [1] They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin.
Hypothetical particles and states of matter that have not yet been encountered, but whose properties would be within the realm of mainstream physics if found to exist. Several particles whose existence has been experimentally confirmed that are conjectured to be exotic hadrons and within the Standard Model .

As of 1 Jan 2024: Uue–Uoq (E119–E184) are listed here by systematic name. That is 66 articles, of which 6 are articles, and 60 are redirects. E172 is predicted to be the end of period 8 ("noble gas", though it may well be reactive or a solid or liquid); in which case E173 would mark the start of period 9.

The graviton is a hypothetical elementary spin-2 particle proposed to mediate gravitation. While it remains undiscovered due to the difficulty inherent in its detection, it is sometimes included in tables of elementary particles. [1] The conventional graviton is massless, although some models containing massive Kaluza–Klein gravitons exist. [17]
In particle physics, the term particle zoo [1] [2] is used colloquially to describe the relatively extensive list of known subatomic particles by comparison to the variety of species in a zoo. In the history of particle physics , the topic of particles was considered to be particularly confusing in the late 1960s.
