Metallic character is the tendency of an element to behave as a metal, for example by losing electrons and forming basic oxides. It decreases with increasing electronegativity, and so decreases across a period and increases down a group. It is the opposite trend to non-metallic character.

金属性是元素表现为金属的倾向,例如失去电子和形成碱性氧化物。它随电负性增大而减弱,故沿一个周期减弱、沿一个族向下增强。它与非金属性的变化趋势相反。
