... If the electrons have two different kinds of spin directions, atoms with those electrons should have different total spins and then they should respond differently to magnetic fields. In the Stern-Gerlach experiment they send these atoms in the x direction between magnets one above the other, where ...

Bohr Model of the Atom
... The Danish physicist Niels Bohr, who first presented this model of the atom, based it on 3 fundamental postulates. (1) Electrons move around the nucleus in circular non-radiating orbits - called “stationary states”. However, they are not at rest! (2) An atom only emits or absorbs electromagnetic rad ...
