The elementary charge, usually denoted by e, is the electric charge carried by a single proton or, equivalently, the magnitude of the negative electric charge carried by a single electron, which has charge −1 e. This elementary charge is a fundamental physical constant. In the SI system of units, the value of the elementary charge is exactly defined as = 1.602176634×10 coulombs, or 160.2176634 zeptocoulombs (zC). Since the 2024 redefinition of S… Webelectron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 11,836the mass of a proton. An electron is therefore considered nearly massless in comparison with a …
