1. Metals

2. What are some metals and their uses
Al : Airplanes, cooking, cans
Fe : Cars, buses
Cu : Wires to carry electricity
Zn : Pennies

3. Properties of Metal How would you describe a Metal?
Smooth?
Shiny?
Hard?
Remember scientist describe matter based on it properties
Physical
Chemical

4. Physical Properties
Malleability
Ductility
Conductivity

5. Malleability
Malleable: material that can be hammered or rolled into flat sheets and other shaps

6. Ductility
Ductile: material can be pulled out or drawn into a wire

7. Conductivity
Conductivity: the ability of an object to transfer heat or electricity to another object

8. Other useful Physical Properties
Some metals are magnetic (attracted to magnets or can be turning into a magnet) Fe Ni Co
Most metals are solids at room temperature
Hg is the exception

9. Chemical Properties
Reactivity is the ease and speed with which an element combines, or reacts, with other elements and compounds
Na reacts strongly with air and water so store it in oil
Au and Pt are valued because they do not react easily with other elements or compounds
Fe is in the middle with a slow reaction to air to form iron oxide, unless protected (corrosion)

10. Alkali Metals First Family React by losing 1 electron
Always found in nature combined with another element
Na and K are essential to your diet
Li is in batteries and medications

12. Alkaline Earth Metals Second Family React by losing 2 electrons
Also only found in nature as a compound
Ca is essential for you
Mg alloys are light weight and strong

13. Transition Metals 3-12 families
Not as reactive as the previous groups, so some can be found un-bonded
Fe is essential for Hemoglobin
Au and Ag are used in jewelry
Cu in pipes and wires

14. Metals in Mixed Groups Some elements in groups 13-15 are metals
Al is in cans and airplane bodies
Sn is used to coat steal and iron so it does not rust
Pb is poisonous, was used in paints and pipes

15. Lanthanides Bottom of table top row Rare earth metals
Mostly used in alloys to improve other metals
Nd makes extremely strong magnets found in hard drives

16. Actinides
Ac, Th, Pa and U are found in nature, others are made in labs
Very heavy and unstable nuclei
Go through decay fast
