When an atom absorbs energy, electrons in the ground state absorb energy and jump to higher energy levels (the excited state). When the electrons fall back to the ground state, they emit the energy they absorbed as visible light radiation of a particular wavelength.
Study with Quizlet and memorize flashcards containing terms like When an atom absorbs a photon containing energy, any of the following can happen except which? The atom is ionized. An electron moves from an upper energy level to a lower one. The atom becomes excited.
When an atom absorbs a photon of light, which one or more of the following can happen? A) an electron shifts to a state of smaller quantum number: B) an electron shifts to a state of higher quantum number: C) an electron leaves the atom: D) b and C.
22 wrz 2016 · The atom absorbs the photon and takes its kinetic energy. That kinetic energy causes increased vibration of the atom which can emit another photon and/or emit a loosely held/ bound electron and/or that vibration can be transmitted to nearby atoms.
If the electron gains energy this is called an absorbance and if it lost energy this is called an emittance. In both cases an energy particle called a PHOTON is absorbed or emitted and thus light is absorbed or emitted.
The electromagnetic spectrum in Figure \(\PageIndex{2}\), for example, shows that absorbing a photon of visible light promotes one of the atom’s or molecule’s valence electrons to a higher-energy level. When an molecule absorbs infrared radiation, on the other hand, one of its chemical bonds experiences a change in vibrational energy.
