Chemically, metalloids correspond to atoms having intermediate electronegativities and an ability to display a range of both positive and negative oxidation states in their compounds. The metalloids or semimetals are elements with properties intermediate between the metals and nonmetals. Typical metalloids have a metallic appearance, may be brittle.

Metalloids are by far the smallest group of elements, as there are only six elements definitively classified as metalloids. They can have anywhere from three to six valence electrons in their. Metalloids and their compounds find applications in a variety of fields including alloys, catalysts, biological agents, glasses, flame retardants, optical storage and.
The metalloids include elements like boron, silicon, and.
This guide will help you recognize, differentiate, and use the concept of metalloids in chemistry. Some periodic tables include a dividing line between metals and nonmetals, and the metalloids may be found close to this line. Each metalloid element takes many forms, but has at least one. Metalloids play a unique role in modern technology and are featured in core science syllabi.
Metalloids are elements with properties between metals and nonmetals, often making them good semiconductors. Metalloids can also be called semimetals.
