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)
WebJun 19, 2024 · The work of Lavoisier and the atomists was furthered in the 18th Century by the British scientist John Dalton. Dalton used the work of Lavoisier and Joseph Proust to examine the ratios of elements that combine to form compounds and look at their ratio of masses. He looked at tin oxide and the combination of masses of oxygen with tin.
