Metals can be hammered into shape without breaking.
What is the reason for this?
The layers of metal ions can slide over each other.
The delocalised electrons can carry an electric charge.
The weak intermolecular forces between atoms are easily broken.
The covalent bonds between the metal atoms are flexible.
