Explain the four quantum numbers

Principal (shell) quantum number - n

Describes the energy level in the atom (1 through 7) The maximum number of electrons in n is 2n2

2. Angular (subshell) quantum number - l

Describes the sublevel in n Each energy level has n sublevels

3. Magnetic quantum number - m

Describes the orbital within l s has 1 orbitalp has 3 orbitalsd has 5 orbitalsf has 7 orbitals

4. Spin quantum number - s

Describes the spin of the electrons in an orbital. Electrons in the same orbital must have oppisite spins. Possible spins are clockwise or counterclockwise.
