Final answer:
Absorption and emission of photons in atoms occur when electrons transition between energy levels, involving the absorption or emission of photons with matching energy differences.
Explanation:
Absorption: During absorption, when an electron moves from a lower energy level to a higher energy level in an atom, it absorbs a photon with energy equal to the energy difference between the levels.
Emission: In emission, when an electron transitions from a higher energy level to a lower one, it releases a photon with energy equal to the energy difference between the levels, resulting in the emission of light.
Changes in the energy levels of an electron in an atom lead to the absorption or emission of photons due to the conservation of energy principle, where the energy of the absorbed photon matches the energy difference between the levels involved, and the emitted photon carries away the excess energy from the electron's transition.
