Lists of metalloids Lists of metalloids This is a list of sources that each list metalloids: elements classified as metalloids. The sources are listed in chronological order. Lists of metalloids differ since there is no rigorous definition of metalloid (or its occasional alias, 'semi-metal'). Individual lists share common ground, with variations occurring at the margins. The elements most often regarded as metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. Wikipedia generally categorises these six as metalloids, with the addition of astatine. Other sources may subtract from this list or add a varying number of other elements. This table show which elements are
Minor metals 40 percent of all production, but that China's share of global production increased 34 percent between 2000 and 2009. Minor metals are used in a wide diversity of end-use applications, from capacitors for consumer electronics (tantalum) and metallic cathodes for rechargeable batteries (cobalt) to photovoltaic solar cells (silicon) and semiconductor materials (gallium and indium).The primary end-uses of minor metals can also help to categorize the metals into four groups: Metals often classified as minor metals include: Antimony (Sb), Arsenic (As), Beryllium (Be), Bismuth (Bi), Cadmium (Cd), Cerium (Ce), Chromium (Cr), Cobalt (Co), Gadolinium (Gd), Gallium (Ga), Germanium (Ge), Hafnium (Hf),
