The subatomic particles considered important in the understanding of chemistry are the electron, the proton, and the neutron. Nuclear physics deals with how protons and neutrons arrange themselves in nuclei. The study of subatomic particles, atoms and molecules, and their structure and interactions, requires quantum mechanics.
Parton, is a generic term coined by Feynman for the sub-particles making up a composite particle – at that time a baryon – hence, it originally referred to what are now called "quarks" and "gluons". Odderon, a particle composed of an odd number of gluons, detected in 2021.

Nuclides with the same atomic mass number, but different atomic and neutron numbers, are called isobars. [8] The mass of a nucleus is always slightly less than the sum of its proton and neutron masses: the difference in mass represents the mass equivalent to nuclear binding energy, the energy which would need to be added to take the nucleus apart.
Its mass is slightly less than the mass of a neutron and approximately 1836 times the mass of an electron (the proton-to-electron mass ratio). Protons and neutrons, each with a mass of approximately one atomic mass unit, are jointly referred to as nucleons (particles present in atomic nuclei). One or more protons are present in the nucleus of ...
Paraparticles, exotic particles that can survive in a 3D-space and follow parastatistics [4] [5] Plektons, particles that follow Braid statistics; Exotic particles, particles with exotic properties like negative mass or complex mass. Exotic hadrons, particles composed of unusual combinations of quarks and gluons. Exotic mesons; Exotic baryons
Mesons named with the letter "f" are scalar mesons (as opposed to a pseudo-scalar meson), and mesons named with the letter "a" are axial-vector mesons (as opposed to an ordinary vector meson) a.k.a. an isoscalar vector meson, while the letters "b" and "h" refer to axial-vector mesons with positive parity, negative C-parity, and quantum numbers I G of 1 + and 0 − respectively.
Accelerons are the hypothetical subatomic particles that integrally link the newfound mass of the neutrino to the dark energy conjectured to be accelerating the expansion of the universe. [19] In this theory, neutrinos are influenced by a new force resulting from their interactions with accelerons, leading to dark energy.
