粒子在確定位置上不停振動，所以固體具有穩固性，有一定的體積和形狀。. 液體 粒子之間的距離比固體的略大，呈不規則的排列，粒子做振動的同時做短距離的自由移動。. 所以液體具有流動性，有一定的體積，但沒有一定形狀。. 氣體 粒子之間的距離很大 ...

The term "particle" is usually applied differently to three classes of sizes. The term macroscopic particle, usually refers to particles much larger than atoms and molecules.These are usually abstracted as point-like particles, even though they have volumes, shapes, structures, etc. Examples of macroscopic particles would include powder, dust, sand, pieces of debris during a car accident, or ...
e. 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. As a consequence of flavor and color combinations and antimatter, the fermions and bosons are known to ...

2024年3月1日 · 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.
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 .
2024年3月26日 · Explore an atom's interior to discover the layout of its nucleus, protons, and electrons. See all videos for this article. 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.
Particles are said to be “indistinguishable” if they are identical to one another. For example, electrons are indistinguishable because every electron in the universe has exactly the same mass and spin as all other electrons—“when you’ve seen one electron, you’ve seen them all.”
