In particle physics, the electron mass (symbol: me) is the mass of a stationary electron, also known as the invariant mass of the electron. It is one of the fundamental constants of physics.
Electron mass me = 9.109 ×10−31 Kilograms. The electron mass value can be expressed through various units like, electron mass in amu, electron mass in eV. Refer the table given below for units along with electron mass value- Rest Mass of Electron.
The invariant mass of an electron is approximately 9.109 × 10−31 kg, [79] or 5.489 × 10−4 Da. Due to mass–energy equivalence, this corresponds to a rest energy of 0.511 MeV (8.19 × 10 −14 J).
Jun 7, 2024 · The lightest stable subatomic particle known, the electron 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 1/1,836 the mass of a proton.
May 21, 2024 · The electron’s mass in kilograms is an extremely small value, approximately 9.109×10^-31 kilograms, reflecting its subatomic nature and the significance of its mass in understanding atomic structure and the behavior of subatomic particles.
The mass of an electron is 9.1093837015 × 10−31 kg. This is called the rest mass of the electron. The rest mass of electrons is denoted as me. According to Einstein’s special theory of relativity, the mass of an electron increases when it is in motion.
The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1 − 1, which is equal but opposite to the charge of a proton, which is +1 + 1.
Aug 30, 2010 · The electron mass or electron rest mass (symbol: me) is a fundamental physical constant. It can be expressed in kilograms, in which case it is determined by the measurement of other physical constants, or as the electron relative atomic mass (symbol: Ar(e) ), the mass ratio of the electron mass to one-twelfth of the mass of a carbon-12 atom ...
Feb 26, 2014 · Stated in kilograms, the electron's mass is around an unimaginable 10 -30 kilogram, or thirty zeros after the decimal point. Although the electron truly is a lightweight, it plays a heavyweight role in nature.
