How well it can replace other metals in a reaction.
For example iron is more active than copper, because
CuSO4 + Fe --> FeSO4 + Cu
reaction occurs. And
Cu + FeSO4 --> no reaction
Its position on the reactivity series. The more reactive the metal, the harder it is to extract from its ore.
The activity (or reactivity) series determines whether or not a metal will replace another one in a replacement reaction.See the Related Questions to the left for more information about the activity series.
Ionisation energy determines the ability to loose electron. It tells the amount of energy changes in the process.
By using the activity series (sometimes called reactivity series) which orders metals by their reactivity with other metals, one can determine the reactivity of a metal
the reactivity increases as you go down the group
total number of electrons
The cheap metal r ing from a vendor is more than gold in reactivity
Decrease reactivity
Low reactivity metals can easily found in earth.
Platinum or Gold.

Metal oxides of high reactivity are soluble in water while those of moderate reactivity are insoluble in water.
