- The mineral galena is composed of lead sulfide. But when lead is found alone and not combined with another element, it is referred to as native lead. 方铅矿这种矿物就是由铅硫化物组成的。但如果铅以单元素形式构成物质而不与其它元素结合,便可称此种矿物为自然铅。
- One is a compound, the other an element, yet both galena and native lead are minerals. 方铅矿和自然铅,虽然一种是由化合物构成,另一种是由单元素构成,但它们二者都是矿物。
