Label each as a metal, nonmetal, or metalloid. Look up properties, history, uses, and more. The elements with the distinguished honor of being called a metalloid are boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po). A rare and highly radioactive metal (although sometimes classified as a metalloid) with no stable isotopes, polonium is a chalcogen and chemically similar to selenium and tellurium, though its metallic character resembles that of its horizontal neighbours in the periodic table: thallium, lead, and bismuth. Silicon (Si) is one of the seven elements that is classified as a metalloid. In addition, a thicker line in the form of a staircase separates the metals from the non-metals and makes it easier to identify the metalloids.
