Properties of Metals

Metallic properties are defined as a substance with the characteristics of luster, good thermal conductor and electrical conductor and the capability of being permanently shaped or deformed at normal room temperature. Metals have following  typical physical properties like Lustrous (shiny), Hard, High density (are heavy for their size), High tensile strength (resist being stretched), High melting and boiling points, Good conductors of heat and electricity Chemical elements not containing the properties are known as nonmetals. A few elements, known as metalloids which sometimes behave like a metal and at sometimes like a nonmetal. Some examples of metalloids are as follows: carbon, phosphorus, tellurium, arsenic, antimony etc.
