Particle - Wikipedia
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...

List of particles - Wikipedia
This is a list of known and hypothesized microscopic particles in particle physics, condensed matter physics and cosmology. 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.

Particle physics - Wikipedia
Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the study of combination of protons and neutrons is called nuclear physics.

In particle physics, an elementary particle is a particle which cannot be split up into smaller pieces. There are many different types of particles, with different particle sizes and properties. Macroscopic particles are particles that are larger than atoms or …
What is the arrangement of particles in a solid, liquid and gas?
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.
