Metalloids are chemical elements that display properties of both metals and nonmetals. On the periodic table, metalloids are found along a zig-zag line between boron and aluminum down to polonium and astatine. Usually, the semimetals or metalloids are listed as boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. Metalloids are also sometimes referred to as semimetals, owing to the fact that metalloids have properties which are in-between metals and nonmetals. This is in accordance with their position on the periodic table of the elements, where they are found between metals and nonmetals.
