Discovery of the electron

i did this report for my chem 1 class, its nothing special, but if you subscribe virtu completelyy info on negatrons, or the discovery of, accordingly 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 component to be identified. The electron is the lightest known particle which possesses an electric cable car charge. Its rest mass is Me equal> 9.1 x 10 -28 g, to the highest tip 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 as 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 faultless direct measurement of e i s the oil drop audition conducted by R.A. Milikan in 1909. In this experiment, the charges of droplets of oil in give vent argon measured by finding the electric spare which balances each drop against its weight. The weight of each drop is hardened by observing its rate of free f all done 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 former(a) decay processes. The electron itself is completely stable. Electrons tote up the mountain to ordinary matter; the volume o f an atom is nearly all occupied by the clou! d of elec trons surrounding the nucleus, which occupies only some 10^-13 of the atoms volume. The chemical properties of ordinary matter are unflinching by the electron cloud.         The electron obeys the Fermi-Dirac statistics, and...
