Web1 aug. 2024 · How an Emission Spectrum Is Produced When an atom or molecule absorbs energy, electrons are bumped into a higher energy state. When the electron drops to a lower energy state, a photon is released equal to the energy between the two states. Web12 sep. 2024 · X-ray production provides an important test of quantum mechanics. According to the Bohr model, the energy of a Kα X-ray depends on the nuclear charge or atomic number, Z. If Z is large, Coulomb forces in the atom are large, energy differences ( ΔE) are large, and, therefore, the energy of radiated photons is large. greater newport physicians hoagWeb26 jul. 2024 · Line spectra are produced when electrons move from one energy level within an atom to another energy level. \ (2\).
