History. Molybdenum (from the Greek molybdos meaning "lead-like") is not found free in nature and the compounds that can be found were until the late 18th century confused with compounds of other elements such as carbon or lead. In 1778 Carl Wilhelm Scheele was able to determine that molybdenum was separate from graphite and lead and isolated the oxide of the metal from
