Metallic Bonding Mechanisms

Describe pure metals precisely as giant structures of identical atoms systematically arranged in a regular, repeating pattern.

Explain how the specific electrons located in the outer shell of metal atoms become wholly delocalised and are thereby completely free to move rapidly through the whole internal structure.

Understand how the widespread sharing of these vast numbers of delocalised electrons inherently gives rise to extremely strong metallic bonds.

Interpret standard representations of metallic bonding explicitly depicted as positive metal ions swimming in a highly mobile sea of delocalised electrons.
