    A metalloid is an element that possesses a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals, and which is therefore hard to classify as either a metal or a nonmetal
  • Metalloid | Definition, Elements, Physical Properties, Chemical . . .
    A metalloid is a chemical element with properties that fall between those of metals and nonmetals These elements share some characteristics with metals, such as luster or moderate conductivity, while chemically behaving more like nonmetals in other contexts
  • Metalloids or Semimetals: Definition, List, Properties, and Uses
    Metalloids show properties of both metals and nonmetals Most are brittle, metallic-looking solids Metalloids are good semiconductors and form amphoteric oxides There are 6–8 elements commonly classified as metalloids Uses include semiconductors, flame retardants, and catalysts
  • What Is a Metalloid? Definition, Properties, Uses
    A metalloid is an element that shares properties of both metals and nonmetals, sitting right at the boundary between the two on the periodic table The most commonly recognized metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium
  • Metalloids: Definition, Properties, Uses, and Applications
    What is a metalloid? 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
