Answer 1

Explanation:

According to reactivity series potassium come first...............??????

Answer 2

Answer:

The reactivity series allows us to predict how metals will react. A more reactive metal will displace a less reactive metal from a compound. Rusting is an oxidation reaction.

The reactivity series

In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a greater tendency to lose electrons and form positive ions.  A reactivity series of metals could include any elements. A good way to remember the order of a reactivity series of metals is to use the first letter of each one to make up a silly sentence. For example: People Say Little Children Make A Zebra Ill Constantly Sniffing Giraffes. Observations of the way that these elements react with water, acids and steam enable us to put them into this series.
