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 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.
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.
- \(m_e=9.1093837\times 10^{-31}kg\)is the mass of an electron.
- The mass of a proton is more than that of an electron. It is almost 1830 times more than the mass of an electron.
- Absoslute mass of an electron is \(1.64\times 10^{-27}kg\) and the charge of an electron is \(1.64\times 10^{-19}C\)
- J.J Thompson established the charge-to-mass ratio of an electron and eventually we derive the mass of an electron by knowing the electron charge.
- \(m_e=9.109\times 10^{-28}g\) is the mass of electron in grams.
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 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
