The protons,neutrons and electrons were very easy to distinguish but the net charges I do not know

Thanks to whoever helps me! I tried all of these questions, but I am getting the wrong answers. Please help mehttp://img171.imageshack.us/img171/1742/…

Though each one I look at, the name of each group changes. I know there are Halogens, Alkali metals, Alkali earth metals, Noble gases, non-metals… What are the rest?
What is the group called where the first element is Aluminium, the group with Scandium and the group down the bottom with Cerium? What are they actually called?
Thanks heaps,
Liana

I have the Partial pressure of water vapor which is 19.8 mm. How do i calculate the partial pressure of hydrogen? Thanks.
