    WEBIn particle physics, 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.

    WEBMar 15, 2024 · The lightest stable subatomic particle known, the electron carries a negative charge of 1.602176634 × 10 −19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10 −31 kg, which is only 1 / 1,836 the mass of a proton.

    WEBThe invariant mass of an electron is approximately 9.109 × 10 −31 kilograms, or 5.489 × 10 −4 atomic mass units. 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.

    WEBAbout. Transcript. Atoms are made up of three types of subatomic particles: protons, neutrons, and electrons. Protons and neutrons are found in the nucleus, the dense region at the center of an atom. Electrons are found outside the nucleus. Protons are positively charged and have a mass of about 1 u.

    WEBThe positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons. The atomic mass unit (amu) is a unit of mass equal to one-twelfth the mass of a carbon-12 atom. Electrons are extremely small.
