Arrange the electrons in the sulfur atom in the orbital diagram

So since there are 16 electrons in sulfur and the first layer of electrons in an orbital shell has a max of two, the first layer will be full. The second layer has a max of 8, so that will also be full. The third layer also has a max of 8 but will not get filled up since there are only 6 electrons left. These are the valence electrons. The orbital diagram will usually look like this:

( O = nucleus, . o = electron)

   o o

o  O  o o

     o

1 a

2 d

3 a

4 c
