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.
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 . It has a value of about 9.109 × 10 −31 kilograms or about 5.486 × 10 −4 daltons , which has an energy-equivalent of about 8.187 × 10 −14 joules ...
Solution. The correct option is C. 9.10938356 × 10 -31. The mass of an electron is approximately 1/1837 times of that of a proton. The mass of an electron in kgs is 9.10938356 × 10 -31.

Mass of 1 electron = Total Mass = 1 Kg number of electrons = Total Mass/Mass of 1 electron = . = = Therefore 1 kg of electrons contains = electrons.
The invariant mass of an electron is approximately 9.109 × 10 −31 kg, 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). The ratio between the mass of a proton and that of an electron is about 1836.
The mass of an electron is \(9.1093837015 \ \times \ 10^{-31} \ kg\). This is called the rest mass of the electron. The rest mass of electrons is denoted as \(m_e\).
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.
Jun 7, 2024 · The rest mass of the electron is 9.1093837015 × 10 −31 kg, which is only 1 / 1,836 the mass of a proton. An electron is therefore considered nearly massless in comparison with a proton or a neutron, and the electron mass is not included in calculating the mass number of an atom.
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
