1. In Current Science, an elementary particle is a particle believed not to have substructure; i.e., it is not known to be decomposable into other particles. An elementary particle is one of the basic building blocks of the universe from which all other things are made. In the Standard Model of Particle Physics, the quarks, leptons, and gauge bosons are elementary particles, along with their antimatter counterparts.
2. In Neu Theory, seven fundamental forms of nature are elementary particles, 3 made of matter and four made of energy.
-  spinrise core – Type I matter
-  spinrise membrane – Type I matter
-  spinrise plasm – Type II matter
- [6+] positive electric charge shell – split spin energy shell(s) surrounding protons and nuclides
- [6-] negative electric charge shell – mirror split spin energy shell surrounding each electron
-  zomon of space – expanding & diffusing-in-place free rise energy pulse
-  photon of radiation – free spin energy bubble carried by moving space
The following five fundamental forms of nature are not considered elementary things by themselves, rather they are movement/synergy projections into space by the natural acceleration of underlying elementary particles:
-  g-spin/magnetic field
-  g-rise/spinfield
- [7+] positive electric field potential energy
- [7-] negative electric field potential energy
-  atomic electric hollow light matrix
The fundamental form of nature, motion  is 2nd law rise energy attached to matter objects, not a thing by itself.
