The energy required to remove an electron from a surface of a solid element is called its work function. If a minimum of 410.1 kJ/mol is required to remove electrons from Bi atoms on a surface of a sample of bismuth, what is the maximum wavelength (λmax) of light that can remove an electron from a Bi atom on this surface? If the same bismuth surface is irradiated with light of λ=239.7 nm, what is the maximum kinetic energy that a released electron could have?
