Electron - Wikipedia
The electron (e −, or β − in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. [13] Electrons belong to the first generation of the lepton particle family, [14] and are generally thought to be elementary particles because they have no known components or substructure. [1]

electron, one of the three basic subatomic particles —along with protons and neutrons —that make up atoms, the basic building blocks of all matter and chemistry. The negatively charged electrons circle an atom’s central nucleus, which is formed by positively charged protons and the electrically neutral particles called neutrons.

2023年2月2日 · Electrons are one of the three types of subatomic particles that make up an atom. The other two types are protons and neutrons. Unlike protons and neutrons, electrons are fundamental particles that cannot be divided further into smaller particles. The standard symbol for an electron is e or e-.
What is an electron? - TechTarget
An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom -- the other two are protons and neutrons. Together, protons and electrons form an atom's nucleus.
