Reactivity of metals GapFill

When a metal reacts with oxygen,  a salta metal acida pure metala metal oxide is formed. During this reaction, the metal is  alloyeddisplacedoxidatedoxidised because it has gained oxygen. Metals can react with non-metals to form  catalystssaltsalloyscarbonates. In these compounds, metals are  positivetranslucentnegativetransparent ions, and more  acidicreactivedensetoxic metals will  chargemagnetisedisplacereact with less reactive metals. Many metals can be placed in an order of reactivity, called  a reactivity seriesa homologous seriesan oxidation columna reduction group, by observing their reactions with water or  dilute acidcopper sulfatenitrogenethanol, because more reactive metals will react more  orderlyslowlyvigorouslysustainably.

Some metals, such as  calciummagnesiumgoldlithium, are considered unreactive, and are found pure in nature. Other metals have to be  neutraliseddugacidifiedextracted from their ores. This is usually done by  a reductiona deoxidationan extractiona carbonisation reaction, where the metal loses oxygen. The metal oxide reacts with  watercarbonhydrogena metal carbonate to form the pure metal and carbon dioxide.

Oxidation and reduction can also be defined another way. Oxidation is the loss, and reduction is the gain, of  metal ionsnitrogenelectronsoxygen. These reactions can be represented using  ionicreductohalfcharge-equations.
