cost of meaning of calcium in metals

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.
