SUMMARY
The Bohr theory establishes a direct relationship between quantized energy levels and angular momentum in atomic physics. Specifically, it states that the angular momentum of an electron is given by the equation mvr = nh/2π, where n is a quantum number and h is Planck's constant. The confusion arises from the units, as nh/2π has units of Joule-seconds (J·s), while angular momentum mvr has units of kg·m²/s. Bohr's framework successfully reconciles these units by demonstrating that angular momentum is quantized, leading to discrete energy levels in atoms.
