Q:

What are metals made from?

A:

Quick Answer

Metals are opaque, lustrous natural elements that are effective in conducting electricity and heat. The majority of metals used in everyday applications are ductile and malleable and are usually denser than other elemental substances.

Full Answer

Metals such as platinum, gold, copper and silver are found in pure forms, while alloys, such as bronze and brass are made by heating two different kinds of metal together and then allowing the mixture to cool. For example, copper and tin are mixed to create bronze, and copper and zinc are used to make brass. By definition, an alloy is a solid material that is made from the mixing of two or more metals. Metals are naturally hard and can be shiny, rough or dull in appearance.

  • Q:

    Why are metals malleable and ductile?

    A:

    Metals are malleable and ductile because they are made of hexagonal and cubic packed structures that can be moved by applying force to them. When force is applied, the atoms slide from one plane past atoms in a different plane.

  • Q:

    What is the difference between metals and nonmetals?

    A:

    The major defining feature of metals is that electrons flow relatively freely between atoms in any object composed of two or more metal atoms, whereas electrons around nonmetals are more tightly bound to their respective nuclei or within individual chemical bonds. This results in other significant features of metal, particularly their high thermal and electrical conductivity. A large majority of known elements are metals.
