A metalloid is a chemical element with properties that are a mixture of both metals and nonmetals. There is no standard definition of a metalloid, nor is there complete agreement as to which elements are appropriately classified as such. Despite this lack of specificity, the term remains in use in the literature of chemistry.

Corrosionpedia explains Metalloid. Metalloids are a group of elements that share characteristics of both metals and nonmetals, and are typically semi-conductors, which means that they both insulate and conduct electricity. This semi-conducting property makes metalloids very useful as a computer chip material.

The origin and usage of the term metalloid is convoluted. Its origin lies in attempts, dating from antiquity, to describe metals and to distinguish between typical and less typical forms. It was first applied to metals that floated on water (lithium, sodium and potassium), and then more popularly to nonmetals.
