Presentation Transcript
A metalloid is a chemical element that has properties that are n between of metals or nonmetals and is consequently difficult to classify a metal or a nonmetal.
Metalloids tend to be economically important because of their unique conductivity properties (they only partially conduct electricity), which make them valuable in the semiconductor and computer chip industry. The metalloids are shown in the following illustration.
The Metalloids are: Boron Boron Silicon Silicon Germanium Germanium Arsenic Arsenic Antimony Antimony Tellurium Tellurium Astatine Astatine

Use Metalloids are used in various industries. They are used in industry and in many biological processes. For example, boron is used in the manufacture of the borosilicate glass. These derivatives are highly resistant to thermal shock. In the form of sodium tetraborate is used for insulation with fiberglass. Boric yarns used in aerospace structures as they are lightweight, but have a high strength. Boron carbide is used in creating bulletproof vests
