How did jj thomson discover electron

WebThomson's measurement convinced him that cathode rays were particles, which were later identified as electrons, and he is generally credited with their discovery. The CODATA recommended value is − e / me = −1.758 820 010 76(53) × 1011 C⋅kg−1. [2] CODATA refers to this as the electron charge-to-mass quotient, but ratio is still commonly used. WebIn the year 1897 J.J. Thomson invented the electron by playing with a tube that was Crookes, or cathode ray. He had shown that the cathode rays were charged negatively. Thomson realized that the accepted model of an …
