How do you determine if an element is a metal?
Most elements are metals. If you've identified your element, go to the periodic table and have a look see. A link is provided to the Wikipedia periodic table, and by looking at it, you can see what is and what isn't. All elements in Group 1 through Group 12 (inclusive) are metals. Group 1 is the alkalai metals, and Group 2 is the alkalai earth metals. Group 3 through Group 12 (inclusive) are the transition metals. The poor metals include those that are left, and they are aluminum, gallium, indium, thallium, tin, lead and bismuth. Note that hydrogen isn't a metal, though it is in Group 1. Note that the periodic table is interactive, and by going to any element's symbol you can link to the Wikipedia article on that element. Why not bookmark the Wikipedia periodic table? You'll quickly be able to find some particulars on any element. And by looking at it now and again, you'll get a feel for the chemistry of some of the elements. This handy tool can really give you a jump on figuring out how chemistry works and why things are the way they are and why they work the way they do.
