Key Stage 3
Meaning
Aluminium is a Group 3 metal element, on the Periodic Table, with an atomic number of 13.
About Aluminium
Molecular Structure
- Aluminium has the chemical symbol Al.
- Aluminium atoms join together in large numbers to form a giant metal molecule.
Atomic Structure
- Aluminium as 13 protons and 14 neutrons in its nucleus giving it an Atomic Number of 13 and an atomic mass of 27.
- Aluminium is in Period 3 of the Periodic Table because it has 3 electron shells.
Properties
- Aluminium is a metal element so it is a good thermal conductor and a good electrical conductor.
- Aluminium is a shiny solid at room temperature.
- Aluminium is malleable.
- Aluminium is sonorous.
