Write the electronic configurations of Al 13 27 and S 16 32 .

In Al 13 27 , the atomic number of Al is 13 . So, the number of electrons is also 13 . Therefore, the electronic configuration of Al = 2 , 8 , 3 . In S 16 32 , the atomic number of S is 16 . So, the number of electrons is also 16 . Therefore, the electronic configuration of S = 2 , 8 , 6 .
