Galena Common Minerals

Galena (lead sulfide) is easily the most important source of lead, and often contains enough silver impurities that it is also a valuable source of that metal. Historically, its ready availability, high density, low melting point, and ease of working made lead one of the first metals to be extensively used by humans, with its known use dating back nearly 8,500 years.

2.7: Nomenclature of Ionic, Covalent, and Acid Compounds

Ionic Compounds . Ionic compounds have a [+] cation and a [-] anion. We use the Principle of Charge Neutrality, that is, for an ionic compound to be stable its chemical formula MUST BE NEUTRAL. So you do not need to state the number of cations and anions, you only need to state what they are (and what their charge is).
