The metalloids in this list include boron, silicon and tellurium. Tin, aluminium, tungsten and bismuth are metals. All metalloids are solids and they can be shiny or dull looking. A metalloid is used because it is a semiconductor and can become more conductive when more light shines on it. A nonmetal is used because it is a poor conductor but can become more conductive when more light shines on it.
