Nonmetal, or non-metal, is a term used in chemistry 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 nonmetal. The elements generally regarded as nonmetals are: ⁕In Group 1: hydrogen ⁕In Group 14: carbon ⁕In Group 15:: nitrogen, phosphorus ⁕In Group 16:: oxygen, sulfur, selenium ⁕In Group 17:: fluorine, chlorine, bromine, iodine, astatine ⁕All elements in Group 18 – the noble gases There is no rigorous definition for the term "nonmetal" – it covers a general spectrum of behaviour. Common properties considered characteristic of a nonmetal include: ⁕poor conductors of heat and electricity when compared to metals ⁕they form acidic oxides ⁕in solid form, they are dull and brittle, rather than metals which are lustrous, ductile or malleable
