Aluminium is used to make overhead power cables and drinks cans.
Give two physical properties of most metals.
Aluminium conducts electricity. Explain, in terms of structure, why metals conduct electricity.
Aluminium can be rolled into thin sheets to make drinks cans. Explain why metals are malleable.
The table shows some data for aluminium, iron and sulfur.
| Element | Melting point in °C | Density in g cm−3\mathrm{g\,cm^{-3}}gcm−3 |
|---|---|---|
| aluminium | 660 | 2.70 |
| iron | 1538 | 7.87 |
| sulfur | 115 | 2.07 |
Use the data to give one way in which aluminium is a typical metal and one way in which it is not a typical metal.
