WebSep 23, 2024 · Electrons have virtually no mass, but protons and neutrons have a lot of mass for their size. As a result, the nucleus has virtually all the mass of an atom. Given its great mass and tiny size, the nucleus is very dense. If an object the size of a penny had the same density as the nucleus of an atom, its mass would be greater than 30 million tons! WebThe 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. [3]
