Metallic Bond (1)

Arrangement of metallic atoms

Arranged closely packed and orderly in the solid state

Formation of metal ions that are positively-charged

When valence electrons are delocalised

Definition of delocalised electron

Electron that moves freely and is not owned by any atom nor ion

Formation of sea of electron

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

The effect when electrons of metal atoms are delocalised in the sea of electrons

The metal can conduct electricity

The reason that enables electrical wires made from metal can conduct electricity (1)

Metal atoms are arranged closely packed and orderly in the solid state

The reason that enables electrical wires made from metal can conduct electricity (2)

Valence electrons of metal atoms can be donated easily and delocalised although in the solid state

The reason that enables electrical wires made from metal can conduct electricity (3)

Metal ions that are positively-charged are formed when valence electrons are delocalised

The reason that enables electrical wires made from metal can conduct electricity (4)

All delocalised valence electrons can move freely between the metal structure and form a sea of electrons

The reason that enables electrical wires made from metal can conduct electricity (5)

Electrostatic attraction force between the sea of electrons and the positively-charged metal ions form the metallic bond
