The energy levels of one-electron atoms

The negative values of the energy for which acceptable solutions of the Schrodinger equation 

Problem 13 Draw a perpendicular energy axis and indicate the three lowest allowed energies of H and He by horizontal hues. Such figures are referred to as orbital energy diagrams. Calculate the energies in kJ mol .

Use the Bohr model to calculate the energy levels of one-electron atoms and to find the freqnencies and wavelengths of light emitted in transitions between energy levels (Section 4.3, Problems 19-22). 

Strictly speaking, the electron mass in the expressions for the energy levels of one-electron atoms should he replaced hy the reduced mass /x, equal to m,m l(mg + where is the nuclear mass /x differs from hy less than 0.1%.
