We are learning to:

• describe metallic bonding as the electrostatic attraction between the positive ions in a giant metallic lattice and a ‘sea’ of delocalised electrons.
• compare the general physical properties of metals and non-metals, including:
• (a) thermal conductivity
• (b) electrical conductivity
• (c) malleability and ductility
• (d) melting points and boiling points

Have you ever wondered why metals like copper do not break easily? Why is it used in electrical wiring?
