Metalloid vs. Semimetal — What's the Difference?

A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids.

A semimetal is a material with a very small overlap between the bottom of the conduction band and the top of the valence band. According to electronic band theory, solids can be classified as insulators, semiconductors, semimetals, or metals.

A nonmetallic element, such as arsenic, that has some of the chemical properties of a metal. Most metalloids behave as semiconductors.

(inorganic chemistry) A metalloid.

A nonmetallic element, such as carbon, that can form an alloy with metals.

An element possessing metallic properties in an inferior degree and not malleable, as arsenic, antimony, bismuth, molybdenum, uranium, etc.

Relating to or having the properties of a metalloid.

Having the appearance of a metal.

(chemistry) An element, such as silicon or germanium, intermediate in properties between that of a metal and a nonmetal; especially one that exhibits the external characteristics of a metal, but behaves chemically more as a nonmetal.

The metallic base of a fixed alkali, or alkaline earth; applied to sodium, potassium, and some other metallic substances whose metallic character was supposed to be not well defined.

(not comparable) Of or relating to the metalloids.

(informal) Characteristic of the metal music genre.

Formerly, the metallic base of a fixed alkali, or alkaline earth; - applied by Sir Humphrey Davy to sodium, potassium, and some other metallic substances whose metallic character was supposed to be not well defined.

Having the appearance of a metal.

Having the properties of a nonmetal; nonmetallic; acid; negative.

Of or being a nonmetallic element that has some of the properties of metal;
