WebA photon is produced when an electron releases energy by moving to a lower energy level within the atom. When the atom absorbs energy, it re-emits it in a random direction, almost instantaneously. The exact time delay is random, but always so fast that it seems pretty much instantaneous. WebThe energy level diagram gives us a way to show what energy the electron has without having to draw an atom with a bunch of circles all the time. ... The electron in this ground …

WebOnly a photon with an energy of exactly 10.2 eV can be absorbed or emitted when the electron jumps between the n = 1 and n = 2 energy levels. The energy that a photon carries depends on its wavelength. Since the photons absorbed or emitted by electrons jumping between the n = 1 and n = 2 energy levels must have exactly 10.2 eV of energy, the ... WebSep 22, 2016 · The whole atom absorbs the energy. Take a hydrogen atom absorbing a photon. You could as well say that the proton absorbed the pboton, but it would be equally fuzzy. In my opinion one should stress that the WHOLE ATOM absorbs the photon and changes energy level for its constituent particles. $\endgroup$ –
