MM that lands off-range are considered WMM if they
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.
