One of the many applications of Coulomb's law is that it can be used to calculate the ionization enthalpies of simple atoms. Calculate the ionization energy for a hydrogen atom. Take atomic radius = 120 pm. Also, determine the wavelength of the light beam that could be used to ionize the hydrogen atom.
