State
In 1913, Niels Bohr proposed an atom's electron occupies only fixed orbits, each with quantized angular momentum and fixed energy, radiating none while in one.
Show
Bohr's quantized-orbit assumption, applied to hydrogen, reproduced the Rydberg equation's structure and matched the measured constant.
Watch for
Bohr's fixed orbits were postulated to match observation — the model gave no reason why only those orbits exist.
