Get PriceAntimony is stable at normal temperatures, but reacts with oxygen when heated. There are four antimony allotropes known. One of allotropes, metallic antimony, is stable, but the other three are metastable. One of the metastatic forms is explosive antimony and produces a white smoke when drawn with a metal object.It has two stable isotopes.
