1) Gold and Copper .
2) Mercury
3) Most reactive = K
Least reactive = Au
4) Aluminium
5) Silver
6) Graphite
7) Oxides of non-metals are generally acidic and neutral in nature .
8) Non-metals do not react with water .
9) Displacement reaction is a reaction in which more reactive element displaces less reactive element.
10) Because they do not give out electrons required for the reduction of hydrogen ions present in acid .
