Web12 de ago. de 2013 · In Niels Bohr’s theory of the atom, electrons absorb and emit radiation of fixed wavelengths when jumping between fixed orbits around a nucleus. The theory provided a good description of the spectrum created by the hydrogen atom, but needed to be developed to suit more complicated atoms and molecules. WebThe 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) In 1906, Robert Millikan's famous oil drop experiment gave the charge on an electron. Only then did it become possible to calculate the mass of an electron. 1 comment
