explain how an atom could emit no x-ray when an outer shell electron falls into a hole in the k shell
When an electron with sufficiently high energy strikes an atom in the X ray tube anode, it ejects an electron from one of atom's inner shells, say the K shell. This leaves an empty slot or hole in this shell. The amount of energy equal to the difference between the energy levels of the two shells. This energy is not required to emit X rays. So an atom could emit no X ray when an outer shell electron falls into a hole in the K shell.

QUESTION 48 During an interaction with an N-shell electron of a tungsten atom, an X-ray is scattered with 15 keV of energy and the electron is ejected with 11.7 keV of kinetic energy. What was the energy of the incident X-ray? Give your answer in keV, rounded to the nearest tenth. But do not include the unit - give only the number portion of your answer. Approximate Number binding of energy Shell electrons (kov) 0.3 L 4 0.01 Carbon- 37...
Consider an atom (not hydrogen) which has a single outer-shell electron, and whose first 4 energies, relative to the ground state, are 0eV, 3eV, 4eV, and 7eV. Its ionization level is 15eV. a) Can a photon with an energy of 5eV be absorbed by the atom when its electron is in level 2? explain b) What initial state (considering only those above) would the electron need to be in for a photon with an energy of 4eV to be emitted?...
