Metallurgy, art and science of extracting metals from their ores and modifying the metals for use. Metallurgy customarily refers to commercial as opposed to laboratory methods. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.

Non-Metals are electronegative elements and tend to share or accept electrons in a chemical reaction. According to physics, non-metals can be defined as elements with a high band gap (activation energy) and, hence, are poor conductors of heat and electricity. In addition, non-metals lack luster and have four or more than four electrons in their valence shell. Of all the elements known, 20 have been found to have non-metallic properties.
