Question

how is the reactivity of a metal summarized in the activity series? how does the placement of a metal in the activity series allow you to predict whether a reaction will, or will not, occur?

Answer 1

The metal with higher reactivity is placed on the top of the series.

• A reactivity series of metals is a list of metals ranging from highly reactive metal to least reactive metal.
• The highly reactive metals are on the top of the list and as we move down the series reactivity of metal decreases.
• Metal being placed above another metal indicates that the former will easily replace the latter from its compound.
• Metals on top have the highest tendency to lose electrons and form a positive ion.
• If the metal of lower reactivity is added to the aqueous solution of metal with higher reactivity then no reaction will be observed.
• If the metal of higher reactivity is added to the aqueous solution of metal with lower reactivity then the reaction will be observed.

So, from this, we can conclude that the metal with higher reactivity is placed on the top of the series.
