A metallic bond is the bonding among metal atoms, introduced here as the third main type of chemical bond alongside the ionic and covalent bonds. It arises from the attraction between positive metal ions and a shared pool of delocalised valence electrons. This model accounts for metals' electrical conductivity, malleability, and lustre.

金属键是金属原子之间的成键,此处作为继离子键和共价键之后的第三种主要化学键引入。它源于正金属离子与一团共享的离域价电子之间的吸引。这一模型解释了金属的导电性、可锻性和光泽。
