WebMetals are widely used because of their properties: strength, ductility, high melting point, thermal and electrical conductivity, and toughness. These properties also offer clues as … WebMetals are usually crystalline solids. In most cases, they have a relatively simple crystal structure distinguished by a close packing of atoms and a high degree of symmetry. Typically, the atoms of metals contain less than half the full complement of electrons in their outermost shell.
