how electron dot structures Determines formula of the ionic compounds formed when aluminum reacts with sulfur?

Answer:

Al has 3 valence electrons S has 6 valence elctrons ..2.Al + 3:S .each empty spot on S will accept an electron until S has 8the 1st Al will share 2 electrons with the 1st S the 2nd Al will share 1e- with a 2nd S and the last 2e- of the 2nd Al will share these with the 3rd ...:S : Al : S : Al:.all atoms possess 8 electrons ....
