به خواندن ادامه دهیدGalena (PbS) is lead sulfide, the principal ore of lead. It is steel gray, heavy (specific gravity is 7.4 to 7.6), and opaque and has a bright metallic silver-colored luster, although the shiny surface may be dulled by a coating of lead carbonate. Galena has a gray or black streak; it is soft enough to mark paper and can be scratched by a penny.
