The non-metal which is liquid at room temperature is: (a) chlorine (b) bromine (c) … In periodic table terms, the counterparts of the highly nonmetallic halogens in group 17 are the highly reactive alkali metals, such as sodium and potassium, in group 1. Most of the alkali metals, as if in imitation of the nonmetal halogens, are known to form –1 anions (something that rarely occurs among metals). Ver mais In chemistry, a nonmetal (or non-metal) is a chemical element that generally lacks a predominance of metallic properties; they range from colorless gases (like hydrogen) to shiny solids (like carbon, as graphite). The Ver mais Physical Physical properties apply to elements in their most stable forms in ambient conditions About half of nonmetallic elements are gases; most of the rest are shiny solids. Bromine, … Ver mais Most nonmetallic elements exist in allotropic forms. Carbon, for example, occurs as graphite, diamond and other forms. Such allotropes may exhibit physical properties that are more metallic or less nonmetallic. Among the … Ver mais Nearly all nonmetals have varying uses in household items; lighting and lasers; and medicine and pharmaceuticals.
