Electron mass

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. 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 or about 0.511 MeV. (Wikipedia).

Atomic number, atomic mass, protons, neutrons and electrons: from fizzics.org

Atomic number and atomic mass together provide key information about an isotope of an element. The two numbers prefix the symbol, the one above giving the atomic mass and the one below the atomic number. The atomic number or proton number defines which element it is. By subtracting that fr
