WebBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr's model calculated the following energies for an electron in the shell, n. n … WebKey points. X-rays are produced by interaction of accelerated electrons with tungsten nuclei within the tube anode. Two types of radiation are generated: characteristic radiation and bremsstrahlung (braking) radiation. Changing the X-ray machine current or voltage settings alters the properties of the X-ray beam.
