1.47 Explain the electrical conductivity and malleability of a metal in terms of its structure and bonding.

• Metals have a high melting and boiling point because there are so many strong metallic bonds, which require a lot of energy to break, especially in giant structures.

• They are good conductors of electricity because their delocalized electrons carry electricity, which means that an electric current passes through very easily.

• Metals are made of layers of atoms which can slide on top of each other, so when force is applied, they slide, making them malleable and change shape relatively easily.
