And I would capitalize the names of the elements when you do that.

In my words, these digrams are a respresentation of how many electrons are located in the outermost(valence) shell of the element.

I'm not sure if you know the structure of each element, it's made of valence shells numbered 1,2,3etc... which each contain electrons in orbit(s) s,p,d,f,etc...

You can actually use electronic configuration tables which list the arrangement for each element in the periodic table,eg. Sulfur's is:

1s² 2s² 2p⁶ 3s² 3p⁴

^{As you can see, sulfur has 3 shells. The third is the outer/valence shell. The superscript on each orbit (the letters s,p,d,f, etc..) indicate the number of electrons. So, you simply add those superscripts associated with the 3rd shell, i.e. 2 + 4 = 6, and you get the electron dot diagram showing six dots, as on the webpage listed.}

^{Note: There is a maximum of eight electrons in a shell.}
