If an atom is in the ground state, and one of its electrons absorbs a photon and jumps to a higher-energy orbit, then we say that this atom is now in an excited state. It almost immediately emits a photon of the same energy and de-excites back to the ground state.

Hello, In Compton scattering, does the electron absorbs a photon and then emit another photon with another energy?? I couldn't understand how would the electron absorb a FRACTION of the photon's energy which is forbidden in QM. Regards ... The electron is ejected from the atom, and the photon is scattered (or re...

When an electron absorbs a photon it gains the energy of the photon. Because an electron bound to an atom can only have certain energies the electron can only absorb photons of certain energies. For example an electron in the ground state has an energy of -13.6 eV.

Atoms like to emit and absorb photons of particular frequencies. ... Roughly speaking, one can think of the electrons as being in orbits in an atom or molecule. But only certain orbits are allowed. For this reason, the atom can have only certain energies. ... energy of emitted photon = (atom energy before) - (atom energy after)

Of all the photons (quantum packets of light energy) that an atom can absorb, ... The electron quantum leaps between orbits proposed by the Bohr model accounted for Plank's observations that atoms emit or absorb electromagnetic radiation only in certain units called quanta. Bohr's model also explained many important...

Since the change in energy is positive, then the atom absorbs a photon of light. The frequency of ... (b) The 2px orbital has a node at the nucleus. The 3s orbital has two nodes at certain distances from the nucleus. ... (b) The element that emits photons of the highest energy will emit photons with the shortest wavelength.
