Metals are elements that occur naturally throughout Earth's surface. All elements of the periodic table are either metals or nonmetals. Most elements of the periodic table are metals, although non-metals are more common on Earth. Metals have common characteristics that they usually shiny, are malleable (easy to form other objects) and conduct electricity well.
Most metals are not naturally in the earth itself, they are usually mixed with another material, and together this thing called "metal connections." One type is referred to as oxides of these compounds. These oxides form a mixture of aluminum and are found in substances called ore. For example, aluminum oxide, the most important metal compound in the ore bauxite is known.
