Be3+ is a one-electron ion. It is a beryllium atom that has lost 3 of its electrons. Minimum energy of a photon that would ionize this ion= -217.6 eV The wavelength of the photon that would excite Be3+ from its ground state to its first excited state= 7.56 nm Calculate the kinetic energy of the photoelectrons if radiation of 4.0 nm of wavelength falls on an ensemble of Be3+ ions.

It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal. How much energy does it take to remove a single electron from an atom on the surface of solid rubidium? J What is the maximum wavelength of light capable of doing this? nm
How much energy is required to cause an electron in hydrogen to move from the n = 3 state to the n = 2 state? b) If the electrons gain this energy by collision between hydrogen atoms in a high temperature gas, calculate the minimum temperature of the heated hydrogen gas. The thermal energy of the heated atoms is given by 3kBT/2, where kB is the Boltzmann constant.
The energy required to remove an electron from a surface of a solid element is called its work function.
