H-like atom: Bohr's model part 1 You carry out a theoretical work on absorption of alpha rays, passing on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus. By introducing conceptions borrowed from Quantum Theory established by Planck, you succeeded in working out and presenting a picture of atomic structure that, with later improvements, still fitly serves as an elucidation of the physical & chemical properties of the elements. You started...

When rubidium ions are heated to a high temperature, two lines are observed in its line spectrum at wavelengths (a) 7.67 x 10-7 m and (b) 3.99 x 10-7 m. What are the frequencies of the two lines? What color are the lines? Choose the answer that best completes the following: The existence of atomic line spectra indicates that. . . the energy of a photon depends on its frequency. all orbitals in s subshells must be spherical in shape....
