1. there are more than 100 elements and some have similar properties as shown on the periodic table of elements. Just WHERE are these elements with similar properties?

2. Where are they located on the Periodic Table of Elements? Look in your book (p. 604-65) for the zigzag line!

3. What are the properties of metals, nonmetals, and metalloids?

4. Draw a triple Venn diagram to compare their properties

5. metals ---- nonmetals Solids at room temp. (except mercury) Most are gases

6. metals ----- nonmetals higher melting pointslower melting points

7. metals ---- nonmetals malleable (can be pounded & shaped) harder brittle (break easily) Softer than metals

8. metals ---- nonmetals Ductile (can be drawn into wire) Not ductile

9. metals ---- nonmetals Has luster (shiny)dull

10. metals ---- nonmetals Good conductors of heat and electricity Poor conductors (good insulators)

11. Metalloids Have some of the properties of metals and properties of nonmetals Include semiconductors (Used in electronics; can conduct but not as good as metals)

12. Steel is an alloy of iron with about 1 percent carbon. It may also contain other elements, such as manganese. Used to make almost everything from skyscraper girders, automobiles, and appliances to thumb tacks and paper clips steel is one of the world's most vital materials.
