Structure and bonding in metals

Metallic bonding

Metals consist of giant structures of atoms arranged in a regular pattern.

The electrons from the outer shells of the metal atoms are delocalised, and are free to move through the whole structure. This sharing of delocalised electrons results in strong metallic bonding.
