Homework Answers
Option A is correct. ( the electron energy levels shows that they depend only upon the principal quantum number. )
Option B is correct. ( The Bohr model states that electrons move in circular orbit around a nucleus)
However, for option C, they are restricted to orbits with only certain energies. Electrons can easily jump from one energy level to another, but they can't have or it's with energies other than the allowed energy levels.

Select true or false for each statement below. True False Electron states are described by orbits, which indicate exactly where an electron is located in an atom. True False The energy levels of all atoms except hydrogen are quantized. True False Electrons move in elliptical orbits around the nucleus of an atom. True False Atoms can gain energy by absorbing a photon. True False When atoms are in an excited state, they can release this energy by emitting light.

Which of the following statements about the quantum-mechanical model of atoms is true? Not only did the Bohr model correctly describe the hydrogen atom and its line spectra, but it also perfectly described more complicated multi-electron atoms. Multiple measurements of the position of an electron around an atom in a particular energy state always find the electron is located at the same distance from the nucleus. There is only one n value for which the angular momentum of an electron...
