نصائح لحل أسئلة Chapter 7

1- always remember that 
l = 0     s orbital
l = 1     p orbital
l = 2     d orbital
l = 3     f orbital
2- the number that comes before S, p, d or f  is the principle quantum number.
3- s, p, d and f are called sub-shells.
4- the s sub-shell doesn't split thus it has only one orbital and ml is always = 0
5- the number of boxes in the following picture tells the number of orbitals in all sub-shell.
