A fundamental constituent of matter. About 200 different elementary particles are thought to exist.
a very small speck of solid matter.
a small part or portion of something, like a particle of sand or dust
A minute quantity of solid or liquid matter.
a form of matter, properties of which could be attributed to a well constrained space and motion of which could be described by a particle motion formalism. motion particle motion natural philosophy
is used here as a synonym for electrons, atoms and/ or electron-deficient atoms (ions) which are in motion, such as in an electric discharge, or in a flowing gas or plasma. So viewed, cosmic rays and stellar/ solar wind ions are particles.
A basic unit of matter or energy.
a bit of matter whose size is small enough relative to our observations that its dimensions may be neglected
a discrete unit of matter having the attributes of mass , momentum (and thus kinetic energy ) and optionally of electric charge
an entity confined to a small volume
a small bit of matter such as an atom , a molecule , or a proton
a small object with properties such as position, velocity, and color
something very tiny atoms are sometimes called particles.
in general, a charged component of an atom, that is, an ion or electron.
A relatively small subdivision of matter ranging in diameter from a few angstroms (as with gas molecules) to a few millimeters (as with large raindrops). A particle can have various shapes and dimensions.
Any of the basic units of matter and energy (such as a molecule, atom, proton, electron or photon).
One of the minute subdivisions of matter
A small piece of material found on a wafer that is not connected with it.
A small piece of matter having negligible dimensions or volume.
a very small piece or part; an indivisible object
A minute constituent of matter, generally one with a measurable mass. The primary particles involved in radioactivity are alpha-particles, beta-particles, neutrons, and protons.
A piece of matter, usually an atom or atomic particle such as an electron, etc.
a very small piece of matter
A piece or small bit of matter.
Relates to coverstocks, particle technology consists of small units of various materials added to the shell. Particle coverstocks provide increased traction in the oil.
A particle is a small piece of something. Click here to go back to where you were.
A very tiny, separate subdivision of matter.
Any of the basic units of matter (e.g., molecule, atom, proton, or electron).
In marine and freshwater ecology, a particle is a small object. Particles can remain in suspension in the ocean or freshwater, however they eventually settle (rate determined by Stokes' law) and accumulate as sediment. Some can enter the atmosphere through wave action where they can act as cloud condensation nuclei (CCN).
