What is the relationship between x-rays and the atomic number?

Best Answers

I presume you mean the X-rays are emitted by an atom with Z protons. Atoms with higher Z bind their core electrons more tightly, so that transitions between a given pair of electron orbitals generate higher energy photons. read more

In a traditional X-Ray tube, electrons are accelerated to a metal target. When hitting the atoms of the target, the electrons will remove electrons from the inner shells of the atoms. These atoms are replaced by electrons from higher shells. The energy differences associated with this process are in the X-Ray range, and depend on the type of atom. read more

In x-ray tubes, the atomic number of the target determines the characteristic x-ray energies. The atomic number determines the binding energy in any material in the beam path, which directly affects the Compton scattering, photoelectric effect, and pair production. read more

Following Bohr's lead, Moseley found that this relationship could be expressed by a simple formula, later called Moseley's Law. Answer #5 | 10/05 2015 09:02 Look into the work of Henry Moseley. read more
