← ScienceWhich outcome occurs when an electron transitions between orbitals?
A)Photon absorption or emission occurs.✓
B)Nuclear fusion reaction triggers.
C)Neutrino flavors oscillate rapidly.
D)Quantum entanglement causes spin reversal.
💡 Explanation
Photon emission/absorption relates to orbital transitions, because electrons emit or absorb photons during quantum transitions, due to the principle of energy quantization and the photoelectric effect; therefore, a photon is emitted, rather than one of the nuclear or entanglement processes.
