Subatomic particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. They include electrons, protons, neutrons, quarks, muons, and neutrinos, as well as antimatter particles such as positrons.
Subatomic particle - 4 Forces, Quarks, Leptons: Quarks and leptons are the building blocks of matter, but they require some sort of mortar to bind themselves together into more-complex forms, whether on a nuclear or a universal scale.
Most of the atom is empty space. The rest consists of three basic types of subatomic particles: protons, neutrons, and electrons. The protons and neutrons form the atom’s central nucleus. (The ordinary hydrogen atom is an exception; it contains one proton but no neutrons.)
Subatomic particle - Current Research, Physics, Quarks: Electroweak theory, which describes the electromagnetic and weak forces, and quantum chromodynamics, the gauge theory of the strong force, together form what particle physicists call the Standard Model.
The Nobel Prize for Physics is awarded, according to the will of Swedish inventor and industrialist Alfred Bernhard Nobel, “to those who, during the preceding year, shall have conferred the greatest benefit on mankind” in the field of physics.
Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.
particle physics, Study of the fundamental subatomic particles, including both matter (and antimatter) and the carrier particles of the fundamental interactions as described by quantum field theory. Particle physics is concerned with structure and forces at this level of existence and below.
The term subatomic particle refers both to the true elementary particles, such as quarks and electrons, and to the larger particles that quarks form. Although both are elementary particles, electrons and quarks differ in several respects. Whereas quarks together form nucleons within the atomic nucleus, the electrons generally circulate toward
subatomic particle, 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.
Atom - Quantum Mechanics, Subatomic Particles, Electrons: Within a few short years scientists developed a consistent theory of the atom that explained its fundamental structure and its interactions.
