Displacement Reactions

• In displacement reactions, metals compete for oxygen or anions
• In displacement reactions oxidization is the loss of electrons
• In displacement reactions reduction is the gain of electrons
• In displacement reactions the more reactive metal will displace the less reactive metal from oxygen or an anion.
• If more reactive metal has oxygen or an anion, no reaction occurs
• The bigger the difference in reactivity between the two metals, the faster the reaction
• Example of displacement reaction: Mg + O2→ 2MgO

  
  

  Here Magnesium is oxidized while the Oxygen atom is reduced
