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
