  2. List of nonmetal monographs - Wikipedia

    en.wikipedia.org/wiki/List_of_nonmetal_monographs

    The purpose of this annotated list is to provide a chronological, consolidated list of nonmetal monographs, which could enable the interested reader to further trace classification approaches in this area. Those marked with a classify these 14 elements as nonmetals: H, N; O, S; the 4 stable halogens; and the 6 naturally occurring noble gases.

  3. Nonmetal - Wikipedia

    en.wikipedia.org/wiki/Nonmetal

    In the context of the periodic table a nonmetal is a chemical element that mostly lacks distinctive metallic properties. They range from colorless gases like hydrogen to shiny crystals like iodine. Physically, they are usually lighter (less dense) than elements that form metals and are often poor conductors of heat and electricity.

  4. List of alternative nonmetal classes - Wikipedia

    en.wikipedia.org/wiki/List_of_alternative...

    Hydrogen is placed by itself on account of it being "so different from all other elements". [6] The remaining nonmetals are divided into nonmetals, halogens, and noble gases, with the unnamed class being distinguished by including nonmetals with relatively strong interatomic bonding, and the metalloids being effectively treated as a third super ...

  5. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

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

  6. Periodic table - Wikipedia

    en.wikipedia.org/wiki/Periodic_table

    Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.

  7. Nonmetallic material - Wikipedia

    en.wikipedia.org/wiki/Nonmetallic_material

    Some textbooks use the term nonmetallic elements such as the Chemistry of the Non-Metals by Ralf Steudel, [25]: 4 which also uses the general definition in terms of conduction and the Fermi level. [ 25 ] : 154 The approach based upon the elements is often used in teaching to help students understand the periodic table of elements, [ 26 ...
