quantum numbers
- the set of numbers used to describe the position and energy of electrons in an atom
principal
quantum
number
- describes the main energy level
angular momentum
- describes the shape of the orbitals in a subshell
magnetic quantum number
- describes the orientation of each orbital in space
spin quantum number
- describes the rotation of spins on how the electron move on their own axis
electron configuration
- is the arrangement of electrons into atomic orbitals, which are described by four quantum numbers.
