It is a scale of how reactive metals are
here it is
potassium most reactive
sodium
calcium
magnesium
aluminium
zinc
iron
tin
lead
silver
gold
platinum least reactive
Low reactivity metals can easily found in earth.
The reactivity of a metal influences its ability to displace another metal in a displacement reaction. A more reactive metal will displace a less reactive metal from its compound. For example, a more reactive metal like zinc can displace copper from copper sulfate because zinc is more reactive than copper.
Sodium metal is usually kept under paraffin because of its high reactivity.
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.
Gold is native in the reactivity series, meaning it is found in its elemental form in nature without needing to be extracted from a compound.
the reactivity increases as you go down the group
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.
The less reactive a metal is, the more likely it is to be found native in the Earth, or the easier it is to extract. By and large, the reactive metals, which are hard to extract, were discovered later.
any metal's that below Copper in the reactivity series.
Lithium
The concept of a metal reactivity series was not invented by a single individual. It is a scientific idea that has been developed over time through the work of many scientists, researchers, and chemists who have studied the reactivity of metals.
To put all six metals in order of reactivity, you can immerse each metal strip in a series of different metal salt solutions with increasing reactivity. Then observe and record the reactions at each stage to determine the relative reactivity of each metal. By comparing the results, you can establish the order of reactivity for all six metals.
Metals higher up the reactivity series (more reactive) will react more readily with oxygen to form the respective metal oxide
No it decreases.
