WebThe ratio of charge to mass of an electron in coulombs per gram was determined by J.J. Thomson. He determined this ratio by measuring the deflection of cathode rays in electric and magnetic fields. What value did he find for this ratio? Q. How did jj thomson arrive at the conclusion that matter was made of electrons. Q. WebThomson was beginning to realize that the cathode rays were discrete charges rather than a mechanism for energy dissipation. By 1895, Thomson’s theory of discharge had evolved; he maintained throughout that gaseous discharge was similar to electrolysis, in that both processes required chemical disassociation. current time london ky
