Question

who derived a quantum model of the hydrogen atom using the emission spectrum of hydrogen atoms?
ernest rutherford
louis de broglie
j.j. thomson
neils bohr

Explanation:

Niels Bohr derived a quantum model of the hydrogen atom using the emission spectrum of hydrogen atoms. His model incorporated quantum theory, stating that electrons orbit the nucleus in discrete energy levels. When electrons transition between these levels, they emit or absorb photons with specific energies corresponding to the differences in energy levels. This explained the discrete lines in the hydrogen emission spectrum.
Ernest Rutherford proposed the nuclear model of the atom based on the gold - foil experiment. Louis de Broglie proposed the wave - particle duality of matter. J.J. Thomson discovered the electron and proposed the plum - pudding model of the atom.
