reactivity of metals

• what is oxidation?

  Loss of electrons, gain of oxygen
• What is reduction?

  gain of electrons, loss of oxygen
• oxidation and reduction always occur together
• when metals react, their atoms lose electrons to form positive metal ions
• the more easily a metal atom loses electrons, the more reactive it is
• reactivity series:

  A) carbon

  B) hydrogen

  C) electrolysis

  D) reduction

  
• metals react with acids to produce metal salts and hydrogen
• what happens in a displacement reaction?


  a more reactive metal will displace a less reactive metal from a solution of its salt
• displacement reaction:

  magnesium + copper sulfate --> copper + magnesium sulfate
