1. A hydrogen atom in a certain excited state has its electron in a 5f subshell. The electron drops down to the 3d subshell, releasing a photon in the process.

a) For each of these subshells, give the n and l quantum numbers, and give the range of possible ml quantum numbers.

b) Determine the wavelength of light which would be emitted by this process.

c) The hydrogen atom now has a single electron in the 3d subshell. Calculate the energy (in kJ/mol) required to ionize this (excited state) hydrogen atom. (This is the energy required to remove the electron completely from the atom.)

d) The photoelectric binding energy of cesium is 183.7 kJ/mol. Light having a wavelength of 2.4m falls upon a cesium surface in an evacuated tube. Calculate the minimum deBroglie wavelength of the emitted photoelectrons.
