The Most Reactive Metal Is
Reactivity series
The reactivity series allows the states to predict how metals will react. A more reactive metal will readapt a less reactive metal from a compound. Rusting is an oxidation reaction.
The reactivity series
In a reactivity series, the near reactive element is placed at the pinnacle and the least reactive element at the lesser. More reactive metals accept a greater trend to lose electrons and course positive ions .
A reactivity series of metals could include whatsoever elements. For example:
A expert way to retrieve the order of a reactivity series of metals is to use the first letter of each i to make up a silly sentence. For instance: P eople S ay L ittle C hildren M ake A Z ebra I ll C onstantly S niffing G iraffes.
Observations of the mode that these elements react with water, acids and steam enable u.s. to put them into this series.
The tables show how the elements react with water and dilute acids:
| Element | Reaction with water |
|---|---|
| Potassium | Violently |
| Sodium | Very quickly |
| Lithium | Quickly |
| Calcium | More slowly |
| Element | Reaction with dilute acids |
|---|---|
| Calcium | Very quickly |
| Magnesium | Quickly |
| Zinc | More than slowly |
| Iron | More slowly than zinc |
| Copper | Very slowly |
| Silver | Barely reacts |
| Gilt | Does not react |
Note that aluminium tin can be hard to place in the correct position in the reactivity series during these experiments. This is because its protective aluminium oxide layer makes it appear to exist less reactive than it really is. When this layer is removed, the observations are more than reliable.
Non-metals in the reactivity serial
It is useful to identify carbon and hydrogen into the reactivity series because these elements can exist used to extract metals.
Here is the reactivity series including carbon and hydrogen:
Annotation that zinc and iron can be displaced from their oxides using carbon but not using hydrogen. Even so, copper tin exist extracted using carbon or hydrogen.
