Radiation from the transition from n=5 to n=3 of He+ shines on a metal surface and ejects electrons. From which of the following metals will electrons be ejected? : Potassium (2.240 eV), calcium (2.710 eV), uranium (3.630 eV), aluminum (4.080 eV), gold (4.820 eV), the values in parentheses are the work functions of each element. Find, by calculating only one speed, the greatest possible speed of the electrons ejected.
