WebHow did Bohr discover his atom model? It was while Bohr was working in England in 1913 that he developed this atomic model. He developed the model after studying the way glowing, hot hydrogen gives off light. When an incandescent light bulb is lit, it gives off all the different wavelengths of light. WebNiels Bohr, (born Oct. 7, 1885, Copenhagen, Den.—died Nov. 18, 1962, Copenhagen), Danish physicist.He studied the structure of the atom with J.J. Thomson and Ernest … 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) sluhn onboarding
