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 ...
Nonmetallic chemical elements are often described as lacking properties common to metals, namely shininess, pliability, good thermal and electrical conductivity, and a general capacity to form basic oxides. [8] [9] There is no widely accepted precise definition; [10] any list of nonmetals is open to debate and revision. [1]
Non-metallic inclusions that arise because of different reactions during metal production are called natural or indigenous. They include oxides , sulfides , nitrides and phosphides . Apart from natural inclusions there are also parts of slag , refractories , material of a casting mould (the material the metal contacts during production) in the ...

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.

Ceramic engineering is the science and technology of creating objects from inorganic, non-metallic materials. This is done either by the action of heat, or at lower temperatures using precipitation reactions from high-purity chemical solutions.
