Explanation / Answer
The second ionization energy (the energy required to remove thesecond outermost electron) of calcium is 11.9 eV. Determine themaximum wavelength of incident radiation that can be used to removethe second electron from a calcium atom? E = h*frequency = h*c/wavelength wavelength = h*c/E = (6.626e-34 Js)*(3e8m/s)/11.9 eV *(1eV/1.60e-19J)*(1e9 nm/1m) = 104.4 nm (nanometers) h = planck's constant c = speed of light
