15.8 eV - 13.6 eV ... or something ... i forgot. just google the ground state energy of H2 atom.
OpenStudy (anonymous):
13.6 eV is the energy of H2 at ground state
OpenStudy (experimentx):
well .. the KE is 2.2 eV ... just convert this in to Joules = 1/2 mv^2 ...
OpenStudy (anonymous):
1eV = 1.6 * 10^-19 j
