Question

Importance of electrons and protons led to their discovery

Answer 1

The Electron was discovered in 1896, by the British physicist J. J. Thomson, using acathode rays while doing discharge tube experiments. ... Through scientific discovery, protons have been accepted as the particle that contributes to the positive charge of an atom.

Answer 2

Explanation:

These protons add the overall positive charge of an atom. The mass of the proton is about 1,840 times the mass of the electron. Through scientific discovery, protons have been accepted as the particle that contributes to the positive charge of an atom. The discovery of protons can be attributed to Rutherford.
