Activity series of metals9/16/2023 ![]() ![]() The reactivity of metals is affected by several factors, including:Įlectron configuration - Metals with fewer electrons in their outer shell are more reactive as they tend to lose them readily.Įlectronegativity - The electronegativity of a metal determines how readily it can form positive ions. It reacts with concentrated acids.įactors Affecting Reactivity Series of Metals Tin - Tin is less reactive than iron but more reactive than lead. It reacts with dilute acids, producing hydrogen gas. Iron - Iron is less reactive than zinc but more reactive than tin. Zinc - Zinc is less reactive than aluminium but more reactive than iron. These metals include zinc, iron, tin, lead, copper, silver, gold, and platinum.Īluminium - Aluminium is less reactive than magnesium but more reactive than zinc. The less reactive metals are the metals that do not react with water or acids. It also reacts with dilute acids, producing hydrogen gas. It reacts slowly with cold water and rapidly with hot water. Magnesium - Magnesium is the fourth most reactive metal in the reactivity series. It also reacts vigorously with water, producing hydrogen gas and a strong alkaline solution.Ĭalcium - Calcium is less reactive than sodium and potassium but still reacts with water, producing hydrogen gas and a weak alkaline solution. Sodium - Sodium is the second most reactive metal in the reactivity series. ![]() It reacts vigorously with water, producing hydrogen gas and a strong alkaline solution. Potassium - Potassium is the most reactive metal in the reactivity series. These metals include potassium, sodium, calcium, and magnesium. The highly reactive metals are the metals that are most likely to react with water and acids. The highly reactive metals are at the top of the list, and the less reactive metals are at the bottom. The reactivity series of metals can be divided into two groups: highly reactive metals and less reactive metals. The following is the reactivity series of metals, arranged in order of their decreasing reactivity: Read more about the Electropositive Elements, Nitride, and Variable Valency.Īrrangement of the Reactivity Series of Metals When we move down the series the electron-donating capacity of metals decreases. While metals from Zinc to Hg can be extracted by simply reducing their oxides, which is an inexpensive method. The metals which are placed above in the series can be extracted by electrolysis. Thus, metals placed at the top of the reactivity series can remove the metals which are present at the bottom of the series from their salts. The metal which is more reactive than other metals can remove less reactive metal from its salt. Metals present in the reactivity series above hydrogen can remove hydrogen ions from dilute HCl or Dilute sulphuric acid. Thus, potassium is the strongest reducing agent.Īs we go down the reactivity series, the ability of metals to remove hydrogen from hydrides decreases. The reducing power of metals decreases as we go down the series. The electropositive character of metals decreases as we go down the series. Metals present at the top of the reactivity series are highly electropositive metals. Salient Features of reactivity series of Metals This knowledge is used in various industrial applications, such as the extraction of metals from their ores and in the production of alloys. For example, if a metal is more reactive than another metal in a compound, it will displace the less reactive metal from the compound. The reactivity series of metals is important in chemistry because it helps predict the outcome of a reaction between a metal and a compound. Why is the Reactivity Series of Metals Important? The table below shows the metals along with their ions. ![]() The more reactive a metal is, the more likely it is to displace another metal from its compound. The reactivity series of metals is based on the ability of metals to displace other metals from their compounds. The most reactive metal is placed at the top of the list, and the least reactive metal is placed at the bottom. The reactivity series of metals is a list of metals arranged in the order of their decreasing reactivity. In this article, we will explain the reactivity series of metals and its importance in chemistry. Some metals react with acids and water, while others do not. However, not all metals have the same reactivity. They are characterized by their high conductivity, ductility, and malleability. Metals are a group of elements that are widely used in various industries and in daily life. ![]()
