Metals are a group of elements that typically exhibit shiny surfaces, good conductivities of electricity and heat, and high melting points. Metallurgy is the science and technology of extracting metals from their ores, refining them, and preparing them for use in various applications.

Most metals are dense due to their atomic structure, which consists of closely packed atoms held together by metallic bonds. This arrangement results in a relatively high density of the material.

Metals are malleable because the electrons in the outer shell of metal atoms are delocalized, meaning they can move freely throughout the material. This allows the metal to be easily deformed without breaking, as the atoms can shift positions while maintaining the metallic bonds.
