Discovery of the electron

i did this report for my chem 1 class, its nothing special, but if you request virtu completelyy info on negatrons, or the discovery of, past this is great. none The stripping Of The Electron         The electron was discovered in 1895 by J.J. Thomson in the form of cathode rays, and was the introductory elementary subatomic particle to be identified. The electron is the lightest known particle which possesses an electric car charge. Its rest mass is Me equal> 9.1 x 10 -28 g, to the highest item 1/1836 of the mass of the proton or neutron.         The charge of the electron is -e = -4.8 x 10^-10 esu trostatic unit). The mansion of the electrons charge is negative by convention, and that of the equ all in ally charged proton is positive. This is somewhat a unfortunate convention, because the flow of electrons in a conductor is blow to the conventional direc tion of the current.         The most hi-fi direct measurement of e is the oil drop look into conducted by R.A. Milikan in 1909. In this experiment, the charges of droplets of oil in note argon measured by finding the electric mere(a) which balances each drop against its weight. The weight of each drop is unyielding by observing its rate of free fall done the air, and using Stokes formula for the viscous drag on a slowly moving sphere. The charges thus measured are intact multiples of e.         Electrons are emitted in radioactivity and in many other(a) decay processes. The electron itself is completely stable. Electrons tote up the mess to ordinary matter; the volume of an atom is nearly all occupied by the cloud of elec trons surrounding the nucleus, which occupies only about(predicate) 10^-13 of the atoms volume. The chemical properties of ordinary matter are unconquerable by the electron cloud.         The electron obeys the Fermi-Dirac statistics, and...
