WebIn 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).They are usually poor conductors of heat and electricity, and brittle or crumbly when solid, due to their electrons having low mobility. WebMay 14, 2024 · Background — Solids. Metals are good conductors. Plastics, wood products, ceramics and glass are insulators. The graphite from a pencil conducts, but has a higher resistance than the metals. Graphite, like silicon, is a semiconductor; it has electrical properties intermediate between insulators and conductors.
WebSimilarly, the substances that have high electron mobility are known as good conductors. And, the ones which do not have good electron mobility are known as bad conductors or insulators.
