... Hydrogen atoms have specific energy levels. Therefore, the atoms can only gain or lose certain amounts of energy. When atoms lose energy, they emit photons which correspond to the lines in the emission spectrum. The more energy lost, the more energy the photon has. Bohr’s model stated that electrons ...
