I'm reading about properties of electrons in atoms, and it says an electron's position in an atom can be described by energy level, shape, orientation, and spin roughly speaking: the energy level (n) dictates the radius from the nucleus (probability wise) the shape (l) dictates... the shape of the orbital the magnetic moment (m_l) dictates the way that shape is oriented (relative to what set of coordinates? I mean "down" isn't towards the center of the earth, I imagine) and spin, which dictates... what the electron does when passed through a magnetic field? a charge that spins generates a magnetic field? the the electron actually rotating about a center axis? thanks!
