A good scientific method is in this order... Ask a question Predict what will happen (hypothesis) Do a test Record data Make a concluion (answer the question) .
With the ecception of th ehalogens, group 17, the groups that have non-metals as the lightest groups 13, 14, 15, 16, the metallic character of the elements generally increaes as you go "down" the group, as the atomic number increases. As you go down a group the ionization potentials drop, it becomes progressivly easier for the electrons to be removed. This is one of the prerequisites for a metallic bond where the s and p electrons are "free to roam". the more obvious concluion is that the formation of cations gets easier which is characteristic of metals.
