Antimony
Antimony is an element present in relatively small concentrations in the earth's crust. It is rarely found in pure form in nature, a fact recognized since antiquity. This may be the source of the name, which comes from the Greek words 'anti' (not) and 'monos' (alone). Antimony compounds are found in several types of ore and in petroleum.Web
