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 ?
