The electro negativity
If an element is below another element in the series the element can't be replaced
a) The chemical principle that forms the basis for the activity series of metals is the reactivity of metals with acids. This principle is known as the "activity of metals." The activity series is a list of metals that ranks them based on their reactivity with certain substances, mainly acids.
To determine the activity series of metals, one can carry out a series of experiments where each metal is placed in a solution of an acid (usually hydrochloric acid) and observe the reaction. Metals that react more vigorously with the acid by producing hydrogen gas or undergoing dissolution are considered more active or reactive. The metals higher up in the activity series are more likely to displace hydrogen from acids and form metal salts.
b) The distance between two metals in the activity series indicates their relative reactivity. Metals that are closer on the activity series will have a more similar reactivity towards acids, while those that are farther apart will have different reactivities.
If two metals are close together in the activity series, it implies that their reactivities with acids are quite similar. Therefore, they will have similar tendencies to displace hydrogen from acids and form metal salts. On the other hand, if two metals are farther apart in the activity series, it suggests that their reactivities with acids differ significantly. In such cases, the metal higher in the activity series will be more reactive and will displace hydrogen from acids more readily than the metal lower in the series.
The significance of the distance between two metals in the activity series lies in understanding their ability to displace each other in chemical reactions. Metals higher in the activity series can displace metals that are lower in the series from their compounds in aqueous solutions. This knowledge is useful in various applications, such as predicting the displacement reactions in redox reactions or determining which metal will corrode when in contact with another metal.
a) The chemical principle that is the basis for the activity series of metals is reactivity. The activity series is a list of metals arranged in order of their reactivity, from the most reactive to the least reactive. This reactivity is determined by the ability of a metal to lose electrons and form positive ions.
b) The significance of the distance between two metals in the activity series is that it determines the ability of one metal to displace another metal from a solution of its salt. Metals higher in the activity series are more reactive, and they have the ability to displace metals lower in the series from their salts in solution. This is because more reactive metals have a stronger tendency to lose electrons and form positive ions, which allows them to easily replace less reactive metals in a chemical reaction.
