An element (e.g. arsenic, antimony, or tin) whose properties are intermediate between those of metals and solid non-metals or semiconductors.
Also called semimetal
Example sentencesExamples
Another group of elements - the metalloid or semi-metal elements - share some properties with the metals and some with the nonmetals.
As its two allotropic forms might suggest, silicon is a metalloid.
Inasmuch as chemical properties determine toxicological properties, metalloids should not be considered as a subset of metals but as a subset of nonmetals.
Chemically, elements can be classified as metals, metalloids, or non-metals based, in part, upon these physical properties.
Separating them are metalloids or semimetals.
