I would really like to know about the properties of the elements - i know its more chemistry than astronomy, but its all related. Why do the elements have the properties that they do, and how can the properties change so markedly by the addition of just one proton and electron, and what gives an element its melting/freezing/boiling point. And its color, hardness, ability to interact with other elements. These are questions I would love Pamela and Fraser to tackle. Shane, Perth Australia

The periodic table on wikipedia has a nice feature that allows you to click through the whole thing. I use it for chemistry class all of the time.
