nonmetal
This term is primarily used in scientific and technical registers, specifically within chemistry and materials science. It functions as a precise classification to distinguish elements like oxygen, carbon, and nitrogen from the metallic elements of the periodic table. While it describes a lack of metallic properties, it is not merely a negative description but a specific category with its own set of chemical behaviors.
When used as an adjective, it often describes materials or components in engineering contexts, such as nonmetal coatings or nonmetal insulators. In these cases, the focus is usually on the functional advantage of the material, such as its resistance to electrical conduction or corrosion, rather than its chemical identity.
Meanings
An element that lacks the characteristic properties of a metal, such as high electrical conductivity and luster.
Examples
Oxygen is a common nonmetal found in the atmosphere.
I wonder if this nonmetal element will react with the catalyst.
We need a nonmetal casing for this device to avoid interference.
