Frequently Asked Questions

What is the mass of an electron?

The electron rest 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 atomic mass units, equivalent to an energy of about 8.187×10 −14 joules or about 0.5110 MeV. Contents.

What is the value of proton mass energy equivalent in MeV?

Click symbol for equation. proton mass energy equivalent in MeV. Numerical value. 938.272 088 16 MeV. Standard uncertainty. 0.000 000 29 MeV. Relative standard uncertainty. 3.1 x 10 -10.

What is MeV in physics?

It is an energy unit used in High-energy physics. A MeV is the Mega electron-volt, e.g. million times more than eV. One eV is defined as the energy, that an electron (or an other single-charged (q=1.6*10^-19 Coulombs) particle) gains when it undergoes a potential difference of 1 Volt.

What is the value of electron rest mass?

Electron rest mass. It is one of the fundamental constants of physics and is also very important in chemistry because of its relation [dubious – discuss] to the Avogadro constant. It has a value of about 9.109×10−31 kilograms or about 5.486×10−4 atomic mass units, equivalent to an energy of about 8.187×10−14 joules or about 0.5110 MeV.
