Revision of the Periodic Table

Hey, I'm revisting the Periodic Table after a one year break and am wondering what resources (preferrably internet) I can gather to further and revise my knowledge. I'm interested in calculating the number of neutrons, protons and electrons by looking at a copy of the Periodic Table, the theory of electron shells, valencies and the chemical addition of metal and non-metal elements.

Look at the atomic number and that will tell you how many protons and electrons it has.

Ya think?
