1. Metallic Bonding

2. Metallic Bonding
Metals form a special type of bond with each other.
Metals often form a lattice in the solid state.
In a metal lattice: 8~12 other metal atoms closely surround each metal atom.

3. Metallic Bonding
In a metal lattice, there is a unique arrangement of electrons.
This is called the electron sea model because all the valence electrons surround all the metals in a metal lattice like a “sea”.

4. Metallic Bonding
In a metal lattice, there is a unique arrangement of electrons.
This is called the electron sea model because all the valence electrons surround all the metals in a metal lattice like a “sea”.

5. Metallic Bonding
The valence electrons that are free to move are called “delocalized electrons.”
A metallic bond is the attraction of a metallic cation for delocalized electrons.

Metal Alloys
An alloy is a mixture of elements that has metallic properties.
Eg. stainless steel, brass, cast iron, bronze, sterling silver

8. Metal Alloys Research Project
Research one alloy in groups of two or three.
Present your research in the form of a powerpoint presentation or a poster that is at least A3 size.
Include all sources
