Homework Help: Binding energy

  1. May 27, 2010 #1
    1. The problem statement, all variables and given/known data
    The energy that binds an orbiting electron to the hydrogen nucleus is 13.4 eV. Calculate the ratio of the binding energy per nucleon to the binding per electron in deuterium. Which particle is held more tightly, the electron or the neutron?

    2. Relevant equations
    using ratios

    3. The attempt at a solution
    basically im having trouble converting from electron volts to the correct units, i know i have to use ratios but what would eV be converted to ?

    the answer i get for deutrieum is (MeV/c^2)/ nucleon how would i convert this to the eV in order to get the correct ratios ( only thing confusing me is the square of the speed of light)

    any help, would i just use the conversion 1eV= 10^-6 MeV , multiply by 10^-6 * 13.4 and use ratios??
