Electron capture and electron transitions.

Click For Summary
SUMMARY

Electron capture occurs when a nucleus captures an electron from the innermost orbit, resulting in a reduction of the proton number by one. This process necessitates adjustments in the energy levels of the atom, compelling electrons to transition to lower energy states. During these transitions, electrons emit electromagnetic (EM) radiation, primarily in the form of X-rays, as they fill the vacancies left by other electrons moving down in energy levels. The emitted radiation is a consequence of the electrons occupying lower energy states after the capture event.

When a nucleus captures an electron from the innermost orbit, its proton number reduces one. Therefore, energy levels in the atom have to change accordingly, meaning all the electrons have to move lower energy levels. From this point of view, during an electron capture, can it be said that the electrons give off EM waves due to the transition between energy levels?

Thank you.

Yes. The effect of changing the energies of the levels because of the change in atomic number is actually pretty small; the bigger effect is that there is now a "hole" in a low energy level, and an electron from a higher level can occupy the hole, emitting EM radiation as it does so (usually the emitted radiation is X rays). That leaves another hole that a still higher electron can occupy, etc., until the new atom is in its ground state.
