Typical metalloids have a metallic appearance, may be brittle and are only fair conductors of electricity. They can form alloys with metals, and many of their other physical properties and. Metalloids are distinctive elements that possess properties intermediate between metals and nonmetals. These intermediate properties include electronegativity, density,. Notice that aluminum borders the line, but it is considered to be a. Depending on how the term is defined, scientists list anywhere from six to nine elements as metalloids. On the periodic table of elements, the metalloids straddle a diagonal. The term “metalloids” (also known as “semimetals”) is used to describe elements that exhibit properties that lie between those typically associated with metals and nonmetals. The term is normally applied to a group of between six and nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) found near. Metalloids can behave like metals or nonmetals depending on the conditions.

For example, silicon is a semiconductor, which means that it conducts electricity better than a.
