is very similar to antimony and bismuth. It exists in bright, metallic forms that are stable in air. It is found free in nature or in combination with other elements, usually sulfur. It is most often used to improve the strength and hardness of alloys, which are combinations of metals. is a gray, shiny metalloid, which is a moderately good conductor of heat and electricity, but gray is brittle and breaks easily.
