the pauli exclusion principle states that 
1- no two electron in an atom can have the same set of all 4 quantum number .. 
2- two electron can have the same value of three quantum number , that is n , l ,m but must have a opposite spin quantum number . 
3- the maximum no of electron in the shell with principal quantum no. n is equal to 2n square . 
AND FOR ELECTRON IC CONFIGURATION , u need to know the other principle also , like haunds rule of maximum multiplicity , aufbaus principle etc . 
and remmebr the sequence , – SSPSPSD , and start filling from the ground level . 
frst read the three principle and then u can do easily . 
ALL THE BEST . 
IF STILL FACING PROB LET ME KNOW .
