The electron (e −, or β − in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.
4 Ιουν 2024 · Electron charge, (symbol e), fundamental physical constant expressing the naturally occurring unit of electric charge, equal to 1.602176634 × 10−19 coulomb. In addition to the electron, all freely existing charged subatomic particles thus far discovered have an electric charge equal to this value.
7 Ιουν 2024 · Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 x 10^-19 coulomb, which is considered the basic unit of electric charge. The electron was discovered in 1897 by the English physicist J.J. Thomson during investigations of cathode rays.
21 Δεκ 2014 · Electrons belong to a group of elementary particles called leptons. There are charged and neutral leptons. And electron is the charged one. But how come it got charged? The negative or positive ch...
Protons, neutrons, and electrons differ in terms of their charge and mass. Let's take a look at charge first. Protons have a positive charge of one plus, and electrons have a negative charge of one minus.
Many fundamental, or subatomic, particles of matter have the property of electric charge. For example, electrons have negative charge and protons have positive charge, but neutrons have zero charge.
8 Δεκ 2018 · An electron is a stable subatomic particle with a negative electrical charge. Unlike protons and neutrons, electrons are not constructed from even smaller components. Each electron carries one unit of negative charge (1.602 x 10 -19 coulomb) and has a very small mass as compared with that of a neutron or proton.
