Class XI Physical Chemistry Short note
... Until 1920 an atom was supposed to consist of only 2 fundamental particles i.e. electrons and protons. Since electrons have negligible mass, the entire mass of the atom was regarded as the mass of the proton only. Each proton has a mass of 1.67x 10-24 g which is taken as 1 unit mass. In 1920, Ruther ...
