- Electrons in multielectron atoms absorb X-rays at characteristic energies, leading to ionization. The characteristic energies for each element allow scientists to identify the element. For magnesium, X-rays with λ = 952 pm are required to selectively eject an electron from the n = 1 energy level, and X-rays with λ = 197 nm remove an electron from the n = 2 energy level.
