Electron Mass Value. Electron mass is sometimes termed as rest mass because according to the special theory of relativity, mass of the object is said to vary according to the frame of reference. Electron mass me = 9.109 ×10−31 Kilograms.
Oct 17, 2023 · Mass of electron or electron mass is \(9.1093837\times10^{-31}\) kilograms. In this Physics article, we will learn about the mass of electron, its value, how it was discovered and its uses in detail.
In particle physics, the electron mass (symbol: m e) 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.
The charge to mass ratio of the electron is given by: e/m = 1.758820 × 1011 C/kg. Where, m = mass of an electron in kg = 9.10938356 × 10-31 kilograms. e = magnitude of the charge of an electron in coulombs = 1.602 x 10-19 coulombs.
The mass of an electron is 9.109 * 10^-31kg. This is called the rest mass of the electron. The rest mass of electrons is denoted as m_e
The electron's mass is approximately 1/1836 that of the proton. Quantum mechanical properties of the electron include an intrinsic angular momentum of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy the same quantum state, per the Pauli exclusion principle.
The electron has mass m_e = 9.1095\times 10^{-28}{\rm\ g}=9.1095\times 10^{-31}{\rm\ kg} = 0.51100 {\rm\ MeV}/c^2, where c is the speed of light. See also: Electron, Electron Charge
Jun 7, 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.
