Look at the periodic table. Above each column, there are usually 2 numbers listed. For example, above Neon's column, there is listed 8A and 18. For the elements in all the A columns, the number listed is the number of valence electrons. Valence electrons are the electrons in the outermost shell. So for neon, it says 8A, so that means there are 8 valence electrons and you would draw 8 dots around the symbol for Neon. Sulfur, look up, it's in column 6A so, 6 valence electrons, so 6 dots around the symbol for Sulfur. Finally, Sodium is in 1A, so 1 valence electron, so 1 dot around the symbol for Sodium.

-
a. Draw symbol for neon, Ne, then put 8 dots around it.

b. Draw symbol for sulfur, S, then put 6 dots around it.

c. Draw symbol for sodium, Na, then put 1 dot around it.
