Which of the following observations led Niels Bohr to formulate his model of the hydrogen atom?

Which statement best describes how the Bohr model explains both the discrete line spectra of hydrogen and the stability of electrons in atoms?

A Bohr model shows a nucleus with 6 protons and 6 neutrons, surrounded by two electron shells: the first shell contains 2 electrons, and the second shell contains 4 electrons. Which element is represented by this Bohr model?

Which of the following electron transitions in the hydrogen atom will result in the absorption of light?

Which statement best describes the orbits of electrons according to the Bohr model?
