Metal - Wikipedia

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as

For example, metals can react with many non-metals: e.g. calcium + chlorine → calcium chloride (Note: When naming a compound the ending of the non-metal is changed to ide) Metals can also react with air (oxygen), water and acids. Some metals react very quickly; they are reactive. Calcium is a reactive metal.

Properties of Metal, Non-metals and Metalloids with Videos

Most non-metals are brittle and are not malleable or ductile. At room temperature, they are usually solids or gases. They usually have low boiling and melting points (except carbon and boron). They are poor conductors of heat and electricity. They are usually less dense when compared to metals. They tend to gain electrons during chemical reactions.
