In 1913 Henry Mosley executed an experiment in which he irradiated neon atoms with high energy X-Rays as well as looked at the resultant kinetic energy of electrons ejected from the neon atoms. From this he was able to conclude the ionization energy for removal of the 1S electron from neon.
Determine the case where Mosley bombarded Beryllium atoms with X-Rays whose photon energy is: 200.9 x 10^-18 Joules each.
Utilizing Ionization energies, compute the left over kinetic energy of the ejected 1S electron when one is dislodged by one energetic X-Ray photon.
1. 1.66 x 10^-16 Joules
2. 1.54 x 10^-17 Joules
3. 1.28 x 10^-18 Joules
4. 1.73 x 10^-16 Joules
5. 5.41 x 10^-16 Joules
