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 kilograms or about 5.486×10 daltons, which has an energy-equivalent of about 8.187×10 joules or about 0.511 MeV. Ver más The term "rest mass" is sometimes used because in special relativity the mass of an object can be said to increase in a frame of reference that is moving relative to that object (or if the object is moving in a given frame of reference). … Ver más Since the electron mass determines a number of observed effects in atomic physics, there are potentially many ways to determine its mass from an experiment, if the values of other … Ver más The electron mass is used to calculate the Avogadro constant NA: $${\displaystyle N_{\rm {A}}={\frac {M_{\rm {u}}A_{\rm {r}}({\rm {e}})}{m_{\rm {e}}}}={\frac {M_{\rm {u}}A_{\rm {r}}({\rm {e}})c\alpha ^{2}}{2R_{\infty }h}}.}$$ Hence it is also … Ver más WebThe Electron's Mass of electron An electron has a mass of electron of 1/1836 that of a proton. Me = 9.10938356 10--31 kilos is the value of electron mass of electron. In physics, the charge of electron and mass of electron of electrons are frequently employed to solve certain problems. Electron charge value of electron in eV
