Electron Charge and Mass Quantity Symbol Value Units Mass me 9.109 x 10-31 kg Charge e 1.602 x 10-19 C I. The Charge to Mass Ratio (e/m) for the Electron Introduction In 1897 J. J. Thompson discovered the first elementary particle, the electron, by measuring the ratio of its charge to mass in a manner similar to the experiment that we will perform. Given the mass and
Specific Charge Experiment. J.J. Thomson's discovery of the electron in 1897 showed us that the atom can be split into even smaller parts. His discovery was the first step towards a detailed model of the atom.
