Someone Mentions That The Electron In A Helium Ion (He+ ) Emits Energy In The From Of Radiation As It Jumps From

Question

Someone mentions that the electron in a helium ion (He+ ) emits energy in the from of radiation as it jumps from

an orbit that has a radius of r (≈ 0.42 nm) to an orbit that has almost half this radius r0 ≈ r/2. Can you estimate the energy carried off by the emitted radiation using a classical model of the electron as orbiting the helium ion? (Express your estimate in terms of properties of the electron like its charge e, mass me, etc. Don’t compute any numbers.)
