v. t. e. Nonmetals 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.
Apr 28, 2024 · 22.2: Hydrogen. Hydrogen can lose an electron to form a proton, gain an electron to form a hydride ion, or form a covalent bond or polar covalent electron-pair bond. The three isotopes of hydrogen—protium (1H or H), deuterium (2H or D), and tritium (3H or T)—have different physical properties. Deuterium and tritium can be used as tracers ...
A nonmetal is a chemical element with several properties that are opposite those of a metal. Based on their properties, the elements of the periodic table are generally classified as metals, nonmetals, and metalloids. [1] Only 18 elements of the periodic table are generally considered nonmetals, whereas more than 80 elements are considered metals.

The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metals; and have at least one basic oxide.
