Unformatted text preview: C. The orientation in space of an atomic orbital is associated with a. the spin quantum number m s b. the magnetic quantum number m l c. the angular momentum quantum number l d. the principal quantum number n D. Atomic orbitals developed using quantum mechanics a. describe exact paths for electron motion b. give a description of the atomic structure which is exactly the same as the Bohr model c. describe regions of space in which one is most likely to find an electron d. allow scientists to calculate an exact volume for the hydrogen atom Chem 127 Dr. Abel Quiz 1C 3. (5 points) Calculate the shortest wavelength photon emitted by the hydrogen atom in undergoing a transition from the n=5 level. Report your answer in nanometers. Shortest wavelength, highest change in energy, so n=5 to n=1 1/ = 1.097 x 10 7 (1/1 2 1/5 2 ) 1/ = 1.053 x 10 7 m-1 = 9.496 x 10-8 m 94.96 nm...
