2. Objective Questions What are the Properties of Metals? How can you Characterize each Family of Metals?

3. Metals Described by… –Hardness –Shininess –Malleability –Ductility

4. Most Metals… Are good conductors –Heat –electricity Magnetic –Fe (iron) –Co (cobalt) –Ni (nickel)

5. Metals have… High melting point –Very useful Except Hg (mercury) –Liquid at room temperature

6. Reactivity Some are very reactive… –Sodium –Potassium Some are not… –Gold –Silver

7. Corrosion The process of oxidizing reaction and wearing away. –Tarnish –Rust

8. Alloys Mixture of 2 or more metals Copper + Tin –Bronze Copper + Zinc –Brass Iron + Carbon + Chromium + Vanadium –Stainless Steel

9. Alkali Metals Lithium to Francium –Extremely reactive Only 1 valence electron –Wants to lose it!

10. Alkaline Earth Metals Beryllium to Radium –Fairly reactive Only 2 valence electrons –Wants to lose them
