Question

The mass of an electron is ................... gm.
​

Answer 1

Answer:

The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units. On the basis of Einstein's principle of mass–energy equivalence, this mass corresponds to a rest energy of 0.511 MeV. The ratio between the mass of a proton and that of an electron is about 1836.

Answer 2

Answer:

 Charge: It is a negatively charged particle.

 Magnitutide of charge: Charge of electron is 1.6022 x 10-19 Coulomb.

 Mass of electron: Mass of electron is 0.000548597 a.m.u. or 9.1 x 10-31 kg.

 Symbol of electron: Electron is represented by "e".

Location in the atom: Electrons revolve around the nucleus of atom in different circular orbits.
