Metals Structure - depts.washington.edu

Metals are widely used because of their properties: strength, ductility, high melting point, thermal and electrical conductivity, and toughness. These properties also offer clues as to the structure of metals. As with all elements, metals are composed of atoms. The strength of metals suggests that these atoms are held together by strong bonds.
