The Chemistry of Metals Flashcards | Quizlet
Metals have delocalised electrons, electrons carry electricity; so because there are free electrons charge can pass easily through a metal. The structure of a metal is with rows of atoms on top of one another, in pure metals as all the atoms will be the same size, the layers can slide easily over one another making them easy to bend.

Lunar Geology: Minerals on the Moon - PERMANENT
Calcium oxides and calcium silies are not only useful for ceramics, but pure calcium metal is an excellent electrical conductor. Calcium metal is not used as a conductor on Earth simply because calcium burns spontaneously when it comes in contact with oxygen (much like the pure magnesium metal in camera flashbulbs).
