a. Radiation from a sodium lamp, such as a streetlight, appears as yellow light and has a wavelength of 589 nm. A burst of yellow light from the lamp contains 609 kJ of energy. How many moles of photons are contained in the burst of light? b. Consider the hydrogen atom with one electron. Determine the wavelength of the photon emitted when the electron drops from a 4d orbital to a 2p orbital in a hydrogen atom. c. Draw the complete orbital diagram (line and arrows) for Sr2+. Label all orbitals. Hint: it might be useful to first write the full electron configuration, then do the orbital diagram. d. Draw the complete orbital diagram (line and arrows) for Co2+. Label all orbitals. Hint: it might be useful to first write the full electron configuration, then do the orbital diagram.
