Which outcome occurs when an excited hydrogen atom relaxes?

💡 Explanation

Photon emission occurs because relaxation leads to spontaneous emission decay from a higher to lower energy orbital. Therefore, a photon is emitted to conserve energy, rather than electron capture or orbital expansion under stable conditions.
