An atom with a first ionization energy of 939 kJ/mol, requires a photon of what maximum wavelength (nm) in order to remove a single electron from a single atom?
In two-photon ionization spectroscopy, the combined energies carried by two different photons are used to remove an electron from an atom or molecule. In such an experiment a gallium atom in the gas phase is to be ionized by two different light beams, one of which has wavelength 403 nm What is the maximum wavelength for the second beam that will cause two-photon ionization? Hint: The ionization energy of gallium is 578.8 kJmol nm Submit Answer 5 question attempts remaining
