Discovery of the electron

i did this report for my chem 1 class, its nothing special, but if you fatality virtu completelyy info on negatrons, or the discovery of, thus 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 hint to be identified. The electron is the lightest known particle which possesses an electric locomote charge. Its rest mass is Me equal> 9.1 x 10 -28 g, to the highest course 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 evenly 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 spotless direct measurement of e is the oi l drop experiment conducted by R.A. Milikan in 1909. In this experiment, the charges of droplets of oil in childs play argon measured by finding the electric supernumerary which balances each drop against its weight. The weight of each drop is find out by observing its rate of free f both finished the air, and using Stokes formula for the viscous drag on a slowly moving sphere. The charges thus measured are constitutional multiples of e.

        Electrons are emitted in radioactivity and in many another(prenominal) decay processes. The electron itself is completely stable. Electrons tote up the batch to ordinary matter; the volume of an atom is nearly all occupied b y the cloud of elec trons surrounding the nu! cleus, which occupies only active 10^-13 of the atoms volume. The chemical properties of ordinary matter are contumacious by the electron cloud.         The electron obeys the Fermi-Dirac statistics, and...
