Conductivity: The measure of a material's ability to conduct electricity. Metals have high conductivity due to their metallic bonding.
Malleability: The property of a substance that allows it to be hammered or rolled into sheets without breaking. This is another characteristic feature of metals due to their unique bonding.
Delocalized Electrons: These are electrons in a molecule, ion or solid metal that are not associated with a single atom or one covalent bond. In metallic bonds, these delocalized electrons allow for properties such as electrical conductivity and malleability.
