  Reactivity series - Wikipedia, the free encyclopedia
The activity series taught in the US is defined by the ease of oxidation and corresponds to the ordering of the table of standard electrode potentials.
The reactivity series determines qualitatively characteristics such as the reactions with water, air and acids as demonstrated above.
The reactivity of these metals are due to the difference in stability of their electron arrangements as atoms and as ions.

 Reactivity - Wikipedia, the free encyclopedia
Reactivity refers to the rate at which a chemical substance tends to undergo a chemical reaction in time.
In pure compounds, reactivity is regulated by the physical properties of the sample.
However in all cases, reactivity is primarily due to the sub-atomic properties of the compound.

 Extraction of Metals - ninemsn Encarta
A metal high in the reactivity series (for example, aluminium) is extracted by electrolysis.
A metal in the middle of the reactivity series, such as iron, is extracted by reduction (see Redox Reactions).
A metal low in the reactivity series, such as mercury, is either found uncombined or extracted by heating alone.

The reactivity series can be established by observation of the reaction of metals with water, oxygen or acids (and also from simple cell experiments).
Not very reactive with dilute sulphuric acid because the colourless calcium sulphate formed is not very soluble and coats the metal inhibiting the reaction, so not many bubbles of hydrogen.
Theoretically its quite a reactive metal but an oxide layer is readily formed even at room temperature and this has quite an inhibiting effect on its reactivity.

As with the alkali metals the reactivity of the group II metals increases as the group is descended, with calcium, strontium and barium all reacting at a reasonable rate.
The more reactive a metal is the more it wants to form compound and therefore the harder it is to isolate the pure metal from its compounds.
The most reactive metals require electricity to extract the metal; less reactive metals can be reduced with coke in a Blast furnace; the least reactive metals are found as the pure metal and require very little purification.

 Chemistry Reactivity Series revision for schools from Etacude.com
The chemical reactivity series for some common elements are shown on the right, with the most reactive elements locate on top and the reactivity behavior decreases when going down the list.
For this reason, an element that is located high in the chemical reactivity series (towards the top of the list) can react explosively with another substance, whereas, elements located further down the list may only react at a slow rate even when heated.
In both cases, as the lesson progresses, look at the reactivity series chart shown on the left and compare the chemical behaviour of the elements.

 The Reactivity or Electrochemical Series
The Reactivity Series is a list of metallic elements, with the strongest metals at the top and the weakest at the bottom.
The reactivity of metals increases as you go down the group because the outer electrons (which are lost when the metal reacts) are further from the nucleus.
The further up the reactivity series a metal is, the more vigorously it reacts with acids.

Magnesium was therefore more reactive, displacement did occur and so it can be placed at the top of my reactivity series.
The reactions between the metal Iron in the Tin chloride solution and the Lead nitrate solution were repeated because I did not believe the results to be true, as at first it was recorded that there were no changes.
This experiment finds the standard electrode potential, the metal with the most electrodes, would be the metal with the electrons most readily lost and so the metal placed highest in the reactivity series.

 Re: Why is the electrochemical series different to the reactivity series?
And yet the standard reduction potential for lithium indicates that it is a stronger reducing agent than potassium.
The important point is that the reactivity series is based on a very general concept of reactivity in a wide variety of different situations.
The electrochemical series is defined with respect to a very particular and special set of conditions -- dilute aqueous solutions at neutral or acidic pH values, or solids (notionally) in contact with water.
