[0002] Metal generally refers to a class of substances that have a unique luster (i.e., strong reflection of visible light) but are opaque, ductile, and have thermal and electrical conductivity. The narrow concept of metal refers to a single substance composed of metal elements. Pure metals are generally solid at room temperature (except mercury). Most of them are excellent conductors of electricity and heat, with high density and high melting point. The metal resources on the earth are widely present in the earth's crust and oceans. Except for a few very inactive metals such as gold and silver, which exist in the form of single substances, the rest exist in the form of compounds. Metals are widely present in nature and are widely used in life. They are a very important and most widely used class of substances in modern industry.
