Antimony Antimony back
Antimony is a metalloid (or semi metal), which is rather metal than nonmetal. Here its stable metallic modification is shown. In its nonmetallic form it is yellow, but unstable. Antimony is important for semiconductors, but has been used for a long time as additive in alloys like bronze and in cosmetics. Nonetheless it is quite toxic and has effects similar to arsenic, but weaker.
