  •  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 nEach energy level has n sublevels  
    3. Magnetic quantum number - m 
     Describes the orbital within ls 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.
