Reactivity of metals GapFill

When a metal reacts with oxygen,  a pure metala metal oxidea metal acida salt is formed. During this reaction, the metal is  oxidiseddisplacedoxidatedalloyed because it has gained oxygen. Metals can react with non-metals to form  alloyscarbonatescatalystssalts. In these compounds, metals are  transparenttranslucentnegativepositive ions, and more  reactiveacidictoxicdense metals will  chargedisplacereact withmagnetise less reactive metals. Many metals can be placed in an order of reactivity, called  a homologous seriesan oxidation columna reactivity seriesa reduction group, by observing their reactions with water or  nitrogendilute acidethanolcopper sulfate, because more reactive metals will react more  orderlysustainablyslowlyvigorously.

Some metals, such as  calciummagnesiumgoldlithium, are considered unreactive, and are found pure in nature. Other metals have to be  acidifiedneutralisedextracteddug from their ores. This is usually done by  a reductiona carbonisationan extractiona deoxidation reaction, where the metal loses oxygen. The metal oxide reacts with  hydrogena metal carbonatecarbonwater 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 ionsnitrogenoxygenelectrons. These reactions can be represented using  chargereductoionichalf-equations.
