1. Metallic Solids 201 Chemistry

2. Kaupapa / Learning Outcome At the end of todays lesson I will be able to explain the properties of metallic solids using their structure and bonding.

3. Metals Eg. Copper, Zinc, Magnesium Low to high melting point Conducts electricity Malleable and ductile

4. Metallic solids Metals are malleable and ductile – Non-directional metallic bonds – It doesn’t matter how the particles are positions as long as they are surrounded by electrons – Malleable – pressed into shape – Ductile – pulled into wires

5. Conducts electricity Both metal solids and liquids conduct electricity Charge is carried by the delocalised electrons

6. Low to High Melting Point Metallic bonds vary in strength and depend on a number of things. – Size of the ions, charge of the ions and number of delocalised electrons
