A hydrogen atom in one of its excited states ha an energy of -1.5129^20 J.

What is the frequency of radiation is emitted when the atom relaxes down to its ground state?

Would you look at your post and proof it please. That 10^20? Is that right?
a hydrogen atom in one of its excited states has an energy of -1.5129x10^-20 J
The energy of the H atom in its ground state is -2.18E-18. Find the difference in the energy, change the negative sign to a positive sign then E = hf and solve for f = frequency. Is that something like 10^15 Hz? You should confirm that.
