1. The Structure of Metals
Physical Science
The Structure of Metals

2. Metallic Bonds
The attraction between a metal cation and the shared electrons that surround it. The cations form a lattice held in place by metallic bonds. The number of valence electrons determines the strength of the metal

3. Explaining Properties of Metals
The ability to conduct electric current.
A metal has a ready supply of charged particles – a pool of shared electrons
Malleability
The lattice is flexible because ions shift positions because of the metallic bond.

4. Alloys
A mixture of 2 or more elements, at least one of which is a metal. The mixture has the properties of metal.

5. Copper Alloys
The Bronze Age was an important era. Made of copper and tin. From BC Brass is another important copper alloy.

6. Steel Alloys
The Age of Steel was the 1900’s.

7. Milestones in Metallurgy
Choose 1 event in metallurgy history. 3 minute presentation on materials – including specific properties of the metals/ alloys involved, applications, and people involved.
