How are metals created
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 ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the metallic bond between the atoms or molecules o… WebAs the reaction between metals and acids produces flammable hydrogen, chemists usually make salts by reacting a metal compound such as a metal carbonate with an acid.
