1 mol of He^(+) ion is excited. Spectral analysis showed existence of 50% ions in 3rd level, 25% in 2nd level and remaining 25% in ground state. Ionization energy of He^(+) is 54.4 eV , calculate total energy evolved when all the ions retirn ground state.

How many times is the ionization energy of He^(+) ion as compared to that of H-atom?

The ionization energy of He^(+) is x times that of H. The ionization energy of Li^(2+) is y times that of H. find |y-x|

If the first ionization enthalpy of Li is 5.4 eV and the elec- tron gain enthalpy of chlorine is 3.6 eV then the Delta H in kcal/mole for the reaction will be Li(g)+Cl(g) to Li^(+) (g) Cl^(-) (g) (Presume that the pressure is so low that the ions do not combine with each other)
