Another quantity named for this man is the (*) most probable distance between the proton and the electron in the ground state of a hydrogen atom.
One quantity named for this scientist is defined as the distance between the electron and the electron hole in an exciton. He's the first namesake of a formalism which sets the action equal to an integer multiple of Planck's constant. The energy shift in the Zeeman effect is equal to the product of the magnetic field, the z-component of the angular momentum, the g-factor, and another quantity named for this man. Another quantity named for this man is the (*) most probable distance between the proton and the electron in the ground state of a hydrogen atom. Those quantities are his namesake magneton and radius. For 10 points, name this Danish scientist who postulated that electrons move around the nucleus in quantized orbits in his namesake atomic model.
