One says to the other, "Are you all right?" "No, I lost an electron!" "Are you sure?" "I'm positive!

Another very useful link!

In addition to the periodic table at the bottom of the page, I've added a link to another really interesting one. This one is color coded in several ways: it tells you whether an element is solid, liquid, or gas at room temperature, and then for each one gives a list of how the element is used as an element, an alloy, and a compound. For instance, if you click on zinc you will see that in black text, indicating as an element, it is used as a corrosion-resistant coating. Then in red text, indicating as an alloy, it is used in car parts and in brass. Finally, in blue text, indicating as a compound, it is used in cosmetics and as a white pigment in rubber. There is a key to explain the use of the table and a ton of interesting information.
