WitrynaAn electron, symbol e −, is one of the fundamental particles that make up matter. The electrons are negatively charged (-1e), almost massless particles that nevertheless account for most of the size of the atom. Their rest mass equals 9.109 × 10 −31 kg ( 510.998 keV/c2) (approximately 1/1836 that of the proton). Witryna20 mar 2024 · One coulomb consists of 6.24 × 10 18 natural units of electric charge, such as individual electrons or protons. From the definition of the ampere, the electron itself has a negative charge of 1.602176634 × 10 −19 coulomb.
