Aluminum has 13 electrons.  
We know, the maximum number of electrons in any energy level (orbit) is given 
by the formula  2n2 ;   n= energy level or Principal Quantum Number. 
It can be shown by simple calculation using the above formula that the first orbit 
(n=1) can accommodate maximum 2 electrons, second orbit (n=2) can 
accommodate maximum 8 electrons, third orbit (n=3)can accommodate 
maximum18 electrons and so on.

Give the values for all four quantum numbers for each electron in the ground state of the aluminum atom.
