The metal, when a metal was exposed to light at a frequency of 7.08 x 1015 51, electrons were emitted with a kinetic energy of 4.97 x 10 19 J. Determine the work function, in kJ/mol and what is the maximum wavelength of light that would cause the emission of a photoelectron? Express your answer in nanometres (nm). 5. 1 level in a B4* cation, a photon of an electron drops from the n = 10 to the n energy is emitted. Does this photon have sufficient energy to cause the ejection of an electron from the above metal (that is, the metal related to both questions above)? Support your answer with one sentence explanation. And you may use Z instead of Zeff in your calculation.
