Discovery of an Electron
A British Physicist named J.J Thompson in the year 1897 proposed that an atom constitutes of at least one negatively charged particle. He named it as “corpuscles” which was later called “electron.”
An electron is represented “e” and it is known to contribute to the negative charge of an atom. The absolute charge of an electron is the negative charge of 1.6×10-19 coulombs. The relative mass of an electron is 1/1836, thus the mass of an electron is very small and is considered as 0.
Discovery of Proton
Proton was discovered by Rutherford when he conducted the famous gold foil experiment. Initially, in 1886 Goldstein discovered the presence of positively charged rays while conducting an experiment in the discharged tube by using perforated cathode. The rays were named as anode rays or canal rays. A series of experiments led to the discovery of protons. Protons are known as the particles that contribute to the positive charge of the atom.
Proton is represented by “p”. The absolute charge of a proton is the positive charge of 1.6×10-19 coulomb. The mass of a proton is 1.6×10 -24 g and is considered 1 that is mass of a hydrogen atom.
