In the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass. [1][2] They vary greatly in size or quantity, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macros...
1. a. : a minute quantity or fragment. b. : a relatively small or the smallest discrete portion or amount of something. 2. archaic : a clause or article of a composition or document. 3. : any of the basic units of matter and energy (such as a molecule, atom, proton, electron, or photon)
What Is a Particle? It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now. Elementary particles are the basic stuff of the universe. They are also deeply strange.
In a solid, the particles pack together tightly in a neat and ordered arrangement. The particles are held together too strongly to allow much movement but the particles do vibrate.
List of particles - Wikipedia. This is a list of known and hypothesized particles. Standard Model elementary particles. 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.
A ll of nature springs from a handful of components — the fundamental particles — that interact with one another in only a few different ways. In the 1970s, physicists developed a set of equations describing these particles and interactions.
In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons.
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.
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Describe the four fundamental forces and what particles participate in them; Identify and describe fermions and bosons; Identify and describe the quark and lepton families; Distinguish between particles and antiparticles, and describe their interactions
