The extent to which cathode rays curved in the presence of a magnet or electrically charged objects depended on the size of the electric charge on the electrons and on the mass of the electrons. THE EXTENT TO WHICH CATHODE RAYS CURVED IN THE PRESENCE OF A MAGNET OR ELECTRICALLY CHARGED OBJECTS DEPENDED ON THE SIZE OF THE ELECTRIC CHARGE ON THE ELECTRONS AND ON THE MASS OF THE ELECTRONS
athode rays carried an electric charge. [Illustration: _J. J. Thomson in his laboratory. On his right are early X-ray pictures._] This view of the cathode rays as consisting of a stream of electrically charged particles was confirmed by another English physicist, Joseph John Thomson (1856-1940). In 1897 he showed that the cathode rays could also be made to take a curved path in the presence of electrically charged objects. The particles making up the cathode rays were charged with negative electricity, judging from the direction in which they were made to curve by electrically charged objects. Thomson had no hesitation in maintaining that these particles carried the units of electricity that Faraday’s work had hinted at. Eventually, Stoney’s name for the units of electricity was applied to the particles that carried those units. The cathode rays, in other words, were considered to be made up of streams of electrons and Thomson is usually given credit for having discovered the electron.  THIS MEANT THAT UNLIKE EITHER LIGHT OR ORDINARY ATOMS THE CATHODE RAYS CARRIED AN ELECTRIC CHARGE THIS VIEW OF THE CATHODE RAYS AS CONSISTING OF A STREAM OF ELECTRICALLY CHARGED PARTICLES WAS CONFIRMED BY ANOTHER ENGLISH PHYSICIST JOSEPH JOHN THOMPSON EIGHTEEN FIFTY SIX NINETEEN FORTY IN EIGHTEEN NINETY SEVEN HE SHOWED THAT THE CATHODE RAYS COULD ALSO BE MADE TO TAKE A CURVED PATH IN THE PRESENCE OF ELECTRICALLY CHARGED OBJECTS THE PARTICLES MAKING UP THE CATHODE RAYS WERE CHARGED WITH NEGATIVE ELECTRICITY JUDGING FROM THE DIRECTION IN WHICH THEY WERE MADE TO CURVE BY ELECTRICALLY CHARGED OBJECTS THOMPSON HAD NO HESITATION IN MAINTAINING THAT THESE PARTICLES CARRIED THE UNITS OF ELECTRICITY THAT FARADAY'S WORK HAD HINTED AT EVENTUALLY STONY'S NAME FOR THE UNITS OF ELECTRICITY WAS APPLIED TO THE PARTICLES THAT CARRIED THOSE UNITS THE CATHODE RAYS IN OTHER WORDS WERE CONSIDERED TO BE MADE UP OF STREAMS OF ELECTRONS AND THOMSON IS USUALLY GIVEN A CREDIT FOR HAVING DISCOVERED THE ELECTRON
