Explanation:
1)n is the principal quantum number . for example if we write 2s1 , 2 denotes the shell number
2)l is different for different subshells
l=0 for s
l=1 for p
l= 2 for d and so on
3)m is calculated using formula : m=2l+1 .
4) s is spin magnetic moment. it denotes the spin of two electrons in an orbital . it can take one of the two values +1/2 or-1/2
