Nonmetal - Wikipedia
WEBNonmetals are chemical elements that mostly lack distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than metals; brittle or crumbly if solid; and often poor conductors of heat and electricity.

Properties of metals, metalloids and nonmetals - Wikipedia
WEBMetalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides.
