Calculate the energy of a single photon corresponding to the n = 7 to n = 5 transition of the Bohr hydrogen atom

What is the minimum value of the principal quantum number (n) when l = 2?

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.

Explain what is incorrect with respect to the following set of quantum numbers: n = 3,1 = -2, m = 0
