Em um metal, cada átomo exerce apenas uma fraca atração nos eléctrons mais externos, da camada de valência, que podem então fluir livremente, proporcionando a formação de íons positivos e o estabelecimento de ligações iônicas com não-metais. Os eléctrons de valência são também responsáveis pela alta condutividade dos metais ...
