2.7 Metallic Bonding and Properties of Metals

Front

Describe metallic bonding.

Back

Electrostatic forces of attraction between positive ions in a giant metallic lattice and a ‘sea’ of delocalised electrons.

Front

Explain good electrical conductivity in metals.

Back

Due to the presence of delocalised electrons that can move freely (mobile electrons).

Front

Explain malleability in metals.

Back

Can be hammered and made into different shapes.

Layers of positive ions can slide past one another easily.

Metallic bonds that are broken can be reformed.
