7. (a). The ionization energy of a particular element is 899 kJ/mol. What is the longest wavelength of light that could provide enough energy to eject an electron from an atom of this element? (8 pts) (10 pts) (b). Suppose an atom of the element above has already absorbed a photon with a wavelength of 345 nm so that it has been promoted to an excited state. What would be the longest wavelength of light that would be able to provide enough energy to eject an electron from the excited atom?
