Lithium Li Displaces H2 gas from water, steam and acids and forms hydroxides. The order of intensity of reactivity is known as reactivity series. These metals are known as noble metals. Reactivity Series of Metals. As example: zinc (Zn) replaces copper from copper sulphate solution. II. Used as insulating material around wire cables since they do not conduct electricity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series. (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. Reaction will take place because Zn is above Cu in the activity series and is more reactive than Cu. GCSE » Chemistry » Metals - The Reactivity Series. This is known as displacement reaction. Reactivity of Non- Metals. Start revising A-level & GCSE with 7 million other students. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. III. The activity series is a list of elements in decreasing order of their reactivity. ... 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. A metal with higher reactivity displaces a metal of lower reactivity. ... Non-metals. Reactivity series of metals and non metals..... - 30542262 amansaroj25253 is waiting for your help. Non-metals react by gaining electrons - they are oxidising agents. The elements which belong to Group VA, VIA, and VIIA are non- metals. Before discussing the reactivity order of metals, it is important to discuss about the differences between metals and non-metals. I. 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. The halogens are a typical example of a non-metal reactivity series. FREE Revision guides, questions banks and resources. Reactivity of element decreases on moving from top to bottom in the given reactivity series. Class 10 Chemistry Metals and Non Metals: Reactivity series: Reactions of metal with other metals: Reactivity series. A metal reacts with another metals and displaces them from their solution. Electrolysis Potassium K Strontium Sr Calcium Ca Sodium Na Magnesium Mg Displaces H2 gas from steam and acids and forms hydroxides. Reaction will not take place as Fe is below Zn in the activity series and cannot displace Zn from its solution. Register Free. A series of metals are arranged on the basis of reactivity and is said to be reactivity series . They are 28 in number. Reactivity series is a list of metals arranged in the order of their decreasing reactivities (activities). 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. Add your answer and earn points. 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) Via, and silver are at the bottom and hence are least reactive typical example of non-metal... - 30542262 amansaroj25253 is waiting for your help from water, steam acids.
