Delocalised electrons: Electrons that are not tied to a specific nucleus, they are free to move around and allow electricity to be conducted.

Giant structure: A constantly repeating lattice structure of molecules, it doesn't end until there aren't enough molecules to add more.
Malleable: Easily bent when force is applied, the opposite of brittle.
