Bohr bury atomic model
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) WebAll elements either emit or absorb certain frequencies of light. Evidence from atomic line spectra supports the Bohr model of the atom using photon frequency calculations.

Sommerfeld’s extension of the Bohr theory in 1915–1916, it was turned into a powerful tool of atomic research and adopted and further developed by German physicists in particular. The new and more general Bohr–Sommerfeld theory described the atom in terms of two quantum numbers, while Bohr had originally used only one quantum number.
