For example, iron (III) oxide can be reduced to iron, as follows : (iii) For obtaining metals that are high up in the reactivity series, their oxides are reduced to metals by electrolysis. The activity series is a list of elements in decreasing order of their reactivity. Electrolysis Potassium K Strontium Sr Calcium Ca Sodium Na Magnesium Mg Displaces H2 gas from steam and acids and forms hydroxides. (ii) For obtaining metals that are in the middle of reactivity series, oxides of such metals can be reduced with coke (carbon) which acts as a reducing agent. C10.2 Reactivity series. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. Reactivity of element decreases on moving from top to bottom in the given reactivity series. I. These metals are known as noble metals. Used as insulating material around wire cables since they do not conduct electricity. ... Non-metals. The order of intensity of reactivity is known as reactivity series. Add your answer and earn points. Before discussing the reactivity order of metals, it is important to discuss about the differences between metals and non-metals. Register Free. They are 28 in number. A series of metals are arranged on the basis of reactivity and is said to be reactivity series . The halogens are a typical example of a non-metal reactivity series. Start revising A-level & GCSE with 7 million other students. Reactivity series of metals and non metals..... - 30542262 amansaroj25253 is waiting for your help. III. A metal reacts with another metals and displaces them from their solution. In the same way that metals can be ordered in terms of reducing strength, the non-metals can be ordered in terms of their oxidising strength. GCSE » Chemistry » Metals - The Reactivity Series. Reactivity Series of Metals. Reactivity of Non- Metals. As example: zinc (Zn) replaces copper from copper sulphate solution. Reaction will not take place as Fe is below Zn in the activity series and cannot displace Zn from its solution. Place in order of reactivity: potassium, sodium, calcium, magnesium, zinc, iron, hydrogen and copper, by reference to the reactions, if any, of the elements with: water or steam; dilute hydrochloric acid (except for alkali metals) A metal with higher reactivity displaces a metal of lower reactivity. II. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series. ... All the elements belonging to lanthanide and actinide series are f- block elements which are also known as inner- transition elements as it is a transit to move from the transition elements of Group IIIB to Group IVB. Lithium Li Displaces H2 gas from water, steam and acids and forms hydroxides. Class 10 Chemistry Metals and Non Metals: Reactivity series: Reactions of metal with other metals: Reactivity series. FREE Revision guides, questions banks and resources. This is known as displacement reaction. Reactivity series is a list of metals arranged in the order of their decreasing reactivities (activities). The elements which belong to Group VA, VIA, and VIIA are non- metals. Non-metals react by gaining electrons - they are oxidising agents.
