Question

Using the ionization energy chart, how much energy will it take to remove only 1 electron on the surface of Nickel? If you hit the surface of Nickel with a photo that has a wavelength of 90nm, what will the wavelength of that ejected electron be?

Answer 1

Do you not have the chart? Can you look up the energy needed to remove one electron? Then plug into the equation I wrote below.
