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
The Law of Conservation of Mass. The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.
