(Select all that apply.) O Valence electrons are the electrons in the outermost energy level. 1s²2s²2p³3s¹ is the electron configuration for an excited state of an oxygen atom. In going from the 2s¹ state to the 1s¹ state, a hydrogen atom would emit a photon of light. An orbital is the same as a Bohr orbit. The wavelength of light is directly proportional to its frequency.

When a hydrogen atom absorbs a photon of electromagnetic radiation (EMR), the internal energy of the atom increases and one or more electrons may be energized into an excited state. The release of this extra energy as the excited state electron transitions back to a lower energy state results in the emission of a photon. These energy changes are responsible for the emission spectrum of hydrogen (shown below) and are described by the Bohr equation. What is the longest wavelength of electromagnetic radiation capable of ionizing this hydrogen atom in an excited state? Report your answer in nanometers.
16) In qualitative terms, how does Bohr's model account for the atomic spectrum of hydrogen? More than one selection may be correct. a) 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. b) The energy released when an electron drops from a higher to lower orbit appears as a photon with the appropriate frequency. c) 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. d) Electrons are found in orbits of arbitrary energy. e) The energy released when an electron drops from a higher to lower orbit appears as a photon with an arbitrary frequency. f) Electron moves around the nucleus along orbits. g) 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.
