In qualitative terms, how does Bohr's model account for the atomic spectrum of hydrogen? More than one selection may be correct. O When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron stays in the orbit having n = 1. %3D O The energy released when an electron drops from a higher to lower orbit appears as a photon with the appropriate frequency. The energy released when an electron drops from a higher to lower orbit appears as a photon with energy equal to the energy difference between the two orbits. Electrons are found in orbits of arbitrary energy. The energy released when an electron drops from a higher to lower orbit appears as a photon with an arbitrary frequency. Electron moves around the nucleus along orbits. When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron is raised from the orbit having n = 1 to a higher orbit, to n = 2 or n = 3 or even higher.
