Question

write one mass of electron in SI UNIT​

Answer 1

Answer:

Fundamental properties. 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.

Mass: 9.1093837015(28)×10−31 kg; 5.48579909070(16)×10−4 u;−1 u; 0.51099895...

Electric charge: −1 e; −1.602176634×10−19 C; −4.80320451(10)×10−10 esu

Symbol: e−, β−

Mean lifetime: stable (> 6.6×1028 yr)

Answer 2

Answer:

1. The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units. ...
2. The invariant mass of an electron is approximately 9.109×10−31 kilograms, or 5.489×10−4 atomic mass units. ...Electrons have an electric charge of −1.602176634×10−19 coulombs, which is used as a standard unit of charge for subatomic particles, and is also called the elementary charge.
