WebThe statement in the video is wrong. In 1897, J. J. Thomson used an electric field (V) to accelerate electrons into a magnetic field (B). The magnetic field deflected the electrons into circular paths of known radius (r). He could then calculate the charge-to-mass ratio (e/m) of the electron. e/m = 2V/ (B²r²)

WebFirst proposed by J. J. Thomson in 1904 [1] soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model represented an attempt to consolidate the known properties of atoms at the time: 1) electrons are negatively-charged particles and 2) atoms are neutrally-charged. extraordinary attorney woo qartuladWebIn 1897, Joseph John Thomson (1856–1940) had announced the discovery of a corpuscle.
