          Mo6-L5a      What is The Periodic Table?


        KEY CONCEPTS:
        1. How does the position of an element on the periodic
          table allow you to determined if the element is metal?
        2. What are some physical properties of metals?


                                                           Malleability
                                                           the ability of a substance to be hammered or rolled

                     Let us learn some vocabulary




        Metal

        an element that is generally shiny, is easily pulled into
        wires or hammered into thin sheets, and is a good
        conductor of electricity and thermal energy

                                                           What is a metal?

                                                           More than three-quarters of the elements on the

                                                           With the exception of hydrogen, all of the elements in
