Any one of the set of elements which, as contrasted with the metals, possess, produce, or receive, acid rather than basic properties; a metalloid; as, oxygen, sulphur, and chlorine are nonmetals.
An element that lacks the properties generally associated with metals.
n element not exhibiting metallic characteristics Chemically, a typical nonmetal accepts electrons from a metal
an element which tends to gain electrons in chemical reactions; one of a class of elements that are brittle, not lustrous, and are generally poor conductors of heat and electricity; nonmetals are grouped on the right side of the periodic table. (see metal)
Substance that does not exhibit the properties of a true metal.
an element that does not exhibit the characteristics of a metal
a chemical element lacking typical metallic properties
not containing or resembling or characteristic of a metal; "nonmetallic elements"
A chemical element that is not classed as a metal because it does not exhibit most of the typical metallic properties. An element that, in general, is characterized chemically by the ability to form anions, acidic oxides and acids, and stable compounds with hydrogen.
an element as specified on the periodic table to be so. Nonmetals are poor conductors. Nonmetals in a solid state are brittle.
(metal,metalloid) non-metal. A nonmetal is a substance that conducts heat and electricity poorly, is brittle or waxy or gaseous, and cannot be hammered into sheets or drawn into wire. Nonmetals gain electrons easily to form anions. About 20% of the known chemical elements are nonmetals.
an element that does not exhibit metallic characteristics. Chemically, a typical nonmetal accepts electrons from a metal.
Nonmetal is a term used in chemistry, used when classifying the chemical elements. On the basis of their general physical and chemical properties, every element in the periodic table can be termed either a metal or a non-metal. (A few elements with intermediate properties are referred to as metalloids.)
