Question

what are electrons ? how they are discovered write mass and charge of one electron​

Answer 1

Answer:

Electrons are the smallest of the particles that make up an atom, and they carry a negative charge. The number of protons and electrons is equal in a neutral atom.Electron was discovered by J. J. Thomson in Cathode Ray Tube (CRT) experiment. The charge of an electron was measured by R. Millikan in Oil drop experiment.

1.602176634 × 10−19 coulomb --- Charge

9.1093837015 × 10−31 kg --- Mass

Which is only 1/1,836the mass of a proton.
