The orbital electrons of an atom can be ejected by exposure to a
beam of electromagnetic radiation. Specifically, an electron can be
ejected by a photon with energy greater than or equal to the
electron's binding energy. A photon's energy (E) is equal to hc/λ,
where h is Planck’s constant, c is the speed of light, and λ is the
wavelength. Calculate the maximum wavelength of radiation
(corresponding to the minimum energy) necessary to eject a 1s
electron from a...
