Metallic Bond (3)

A sea of electron

Formed when the valence shells of metal atoms overlap, resulting in electron delocalisation

Electrical conductivity of copper (1)

The valence electrons of the copper atom can be easily donated and delocalized in the solid state

Electrical conductivity of copper (2)

All delocalized electrons can move freely between the metal structure and forming a sea of electrons

Electrical conductivity of copper (3)

Electrons that move freely carry electric charge from the negative terminal to positive terminal and conducts electricity in the electrical wire

The effect of exposed electrical wires

Can cause electric shock
