Bohr atom: the physics behind the Rydberg formula 1. Electrons move in circular orbits around the atomic nucleus, their motion being described by classical physics. 2. Fixed set of stationary states (allowed orbits) are characterized by discrete angular momenta (l) values: nh/2 ! , n=1, 2, 3…. 3. The allowed, integral values of l are called quantum numbers. 4. Energy packets (quanta) are absorbed or emitted when electrons change stationary states.

Ionization Energy of Hydrogen " E = hc R H ( n i 2 1 n f 2 1 ) = h ! As n f goes to infinity : h ! = hc R H ( n i 2 1 ) = hc R H This also works for hydrogen-like species such as He + and Li 2+ . h ! = Z 2 hc R H
