 * Lecturette: Metals in the Periodic Table **

Metals are all around you. The cars and buses you ride in are made of steel, which is mostly iron. Airplanes are covered in aluminum. A penny is made of zinc coated with copper. Copper wires carry electricity into lamps, stereos, and computers. It’s hard to imagine modern life without metals.

Think about what you already know about the metals that you use on a daily basis. Listed below are the six families of metals on the Periodic Table of Elements. Each metal is classified and then placed into a family group based on its properties. Use this material as a review to enhance your understanding of the metals on the periodic table. While you’re reading, think about how specific metals and their properties can impact your life. Why? How?

Studying the objectives and links below will improve your review.

**Lesson Objectives: **
 * Explain the properties of alkali, alkaline earth, transition, metals in mixed groups, lanthanides, and actinides.
 * Explain how the reactivity of metals changes across the periodic table
 * Explain how the elements that follow uranium are produced
 * Discuss how and why metals have impacted your life
