Definition of subatomic in English English dictionary
Relating to any length or mass that is smaller in scale than a the diameter of a hydrogen atom
The electron microscope is able to resolve detail at the subatomic level.
Relating to particles that are constituents of the atom, or are smaller than an atom; such as proton, neutron, electron, etc
of dimensions smaller than atomic dimensions of or relating to constituents of the atom or forces within the atom; "subatomic particles"; "harnessing subatomic energy
of or relating to constituents of the atom or forces within the atom; "subatomic particles"; "harnessing subatomic energy"
{s} of or pertaining to particles within an atom; of or pertaining to processes occurring within an atom
A subatomic particle is a particle which is part of an atom, for example an electron, a proton, or a neutron. smaller than an atom or existing within an atom
Any of various units of matter below the size of an atom, including the elementary particles and hadrons. or elementary particle Any of various self-contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but heavy core. By the early 1930s it was found that the nucleus is composed of even smaller particles, called protons and neutrons. In the early 1970s it was discovered that these particles are made up of several types of even more basic units, named quarks, which, together with several types of leptons, constitute the fundamental building blocks of all matter. A third major group of subatomic particles consists of bosons, which transmit the forces of the universe. More than 200 subatomic particles have been detected so far, and most appear to have a corresponding antiparticle (see antimatter)
