Metalloids

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

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.


Metalloids

The Metalloids are:

Boron

Silicon

Germanium

Arsenic

Antimony

Tellurium

Astatine

Properties of Metalloids

Physical Properties of Metalloids

State of Matter is Solid

Elasticity is Brittle

Luster is Metallic

Conductivity is Semi-conductive

Chemical Properties of Metalloids


Metalloids

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
