[SEMATECH] Elements with the Highest Reactivity. A great example of such a reaction is the displacement of copper from copper sulfate by zinc. Less energy is needed to isolate the metallic elements from their compounds. (a) Explain with an example how the metal (X) which is low in reactivity series and metal (Y) which is high in the reactivity series are obtained from their compounds by reduction process. Reactivity Trend in the Periodic Table . Reactivity series of metals. Required fields are marked *, Long Tabular Form of the Reactivity Series. Since magnesium is more reactive than carbon dioxide, the magnesium reduces carbon dioxide to carbon and become magnesium oxide itself. Therefore, the reactivity series of metals can be used to predict the reactions between metals and water. The data provided by the reactivity series can be used to predict whether a metal can displace another in a single displacement reaction. A metalâs reactivity can be worked out by studying its reactions in both the reactions to competition and displacement. The most reactive metals react with cold water to yield the metal hydroxide and hydrogen gas. Magnesium reacts slowly with cold water, but quickly with boiling water or acids. The noble metals only react with strong oxidizers, such as aqua regia. Despite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals. The reactivity series is a list of metals ranked in order of decreasing reactivity, which is usually determined by the ability to displace hydrogen gas from water and acid solutions. The major disadvantage of using standard electrode potentials is that they only apply to aqueous solutions under standard conditions. If the reaction occurs when a metal is put into an aqueous solution of another metal ion, the reactivity of the inserted metal is more higher than the metal in solution. The reactivity series follows the order, from most reactive to least reactive: Thus, cesium is the most reactive metal on the periodic table. 1. The most reactive metals are on the bottom left side of the periodic table. [ 1 ] [ 2 ] [ 3 ] It is used to summarize information about the reactions of metals with acids and water , single displacement reactions and the extraction of metals … The ions of low ranking metals are readily reduced by high ranking metals on the reactivity series. (a) The series of metals in which metals are arranged in decreasing order of their reactivity. The most chemically reactive metal is francium. This concept has several practical applications in the extraction of metals. Metals react differently with different substances. One of the common compounds formed by metals is metal oxide. Thus, the reactivity series of metals can also be used to predict the outcome of single displacement reactions. The relative reactivity of metals can be used to organize them into an activity series. (c) CuSO 4 (aq.) Most reactive metals are at top while least reactive metals at the bottom. The reactivity series is a series of metals, in order of reactivity from highest to lowest. A metal will displace any metal lower in the series. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. Apart from providing insight into the properties and reactivities of the metals, the reactivity series has several other important applications. Likewise, non-metals are poor heat conductors, and solid non-metals are dull and brittle. Reactivity decreases. Electrochemical series can be used to predict variousproperties of an element based on their position in the series relative to thehydrogen electrode.
