On the other hand, the term "elementary charge" is unambiguous: it refers to a quantity of charge equal to that of a proton. Lack of fractional charges Paul Dirac argued in 1931 that if magnetic monopoles exist, then electric charge must be quantized; however, it is unknown whether magnetic monopoles actually exist.

Charge élémentaire. En physique, la charge élémentaire est la charge électrique d'un proton ou, de façon équivalente, l'opposé de la charge électrique d'un électron. Elle est notée e et s'exprime en coulombs ( C ), ou en A s dans le Système international d'unités. Elle a été mesurée pour la première fois en 1909 par le ...
19 ott 2019 · 4. The electron is an elementary particle, part of the SM, pointlike, with no substructure, or spatial extent. Its intrinsic properties include its EM charge, which we still call the elementary charge. Originally the name electron comes from electric ion, and it was discovered around the 1900s. Though we still call it (the electron's Em charge ...
The fundamental unit of charge (also called the elementary charge) equals the magnitude of the charge of an electron (e) with e = 1.602 \(\times\) 10 −19 C. A proton has a mass of 1.0073 amu and a charge of 1+. A neutron is a slightly heavier particle with a mass 1.0087 amu and a charge of zero; as its name suggests, it is neutral.
