introduction

In this power point I will be researching on 6 metals on the reactivity series and conclude and explain the relationship between ldquothe reactivity of the metal and when it was discoveredrdquo I would be writing up about them eg when was it discovered who discovered it how it was extracted what are its uses its relationship and its description

REACTIVITY SERIES

IRONDISCOVERY DATE 2500 - 3500 BCWHO DISCOVERED IT G A WainwrightHOW WAS IT EXTRACTED The first sources of Iron came from meteors they

smelted the iron began in Anatolia or the CaucasusRELATIONSHIP as you can see iron was discovered during 3500BC compared to

Sodium was discovered during year 1807 so you can see here that the less reactive metal is Iron less reactive metals are usually found first because less reactive metals are nearer to the earths surface example in a metals and acids lab we placed iron into acid and there were tiny bubbles rising to the surface popping sounds didnrsquot heat up alot and it doesnt float And as you can see in the reactivity series above Iron is categorized as a metal that reacts with acids meaning its quite reactive

USES OF THE METAL Iron plays a big part in our daily lives it is used to make almost everything around us it is used to manufacture steel it is used to make cars trucks airplanes building structures ships computers furniture office supplies and so on

IRONDESCRIPTION

Iron is metallic shiny smooth bright white metal that is soft malleable ductile and strong Its surface is usually discolored by corrosion

SODIUMDISCOVERY DATE year 1807WHO DISCOVERED IT Humphry DavyHOW WAS IT EXTRACTED It was extracted through the electrolysis of caustic sodaRELATIONSHIP As you can see sodium was found quite recently it is the most reactive metal

on the reactivity series and since it was discovered quite recently so that means that is it extremely reactive because all reactive metals are usually found deep within the earth therefore taking a much longer time to discover it it categorized under metals that are soo reactive that it even reacts with water

USES OF THE METAL Since it is such a highly reactive metal by itself it has only a few uses to it Sodium is used by the body in order to regulate blood and body fluids If the body is lacking this mineral the person can become sick and have muscle cramps He or she may also feel dizzy or even have diarrhea The kidneys ability to retain water will also be affected by this Sodium is used in certain alloys in order to make their structure better It is also used in soap as it is mixed with fatty acids These soaps are harder than soaps that are made with potassium Uses of sodium also include being used in order to make the surfaces of metals smoother and to make molten metals more pure Sodium chloride is common salt and it is the most important compound involving sodium

SODIUMbull DESCRIPTIONSodium is a grey metal it is shiny and very soft it can be cut with a knife In air they turn white in seconds when exposed to water

they generate hydrogen gas and explode in flaming balls of molten sodium

Aluminumbull DISCOVERY DATE year 1825bull WHO DISCOVERED IT Hans Christian Oerstedbull HOW WAS IT EXTRACTED He extracted it by having anhydrous aluminum chloride

react with potassium amalgam to produce a chunk of metal with properties similar to those of tin

bull RELATIONSHIP Aluminum was found not long ago meaning its quite reactive because the later the metal is found the more reactive it is because more reactive metals are found deep within the earths surface aluminum reacts with acids there fore it is quite reactive

bull USES OF THE METAL Aluminum is used excessively in the modern world and the uses of this metal are extremely diverse No other metallic element can be used in so many ways across such a variety of domains like in the home in transport on land sea and in air and in industry and commerce One of the most common end uses of aluminium is packaging including drinks cans foil wrappings bottle tops and foil containers it is also used to manufacture glass and is also used to make parts in airplanes boats and ships and several car parts it is used to make alot of household items like door knobs kettles window frames etchellip (continue to next slide)

ALUMINUMDESCRIPTION Aluminum it shiny and metallic extremely light the reason why it is so commonly used today

Gold DISCOVERY DATE it was discovered so early no one can verify WHO DISCOVERED IT its discovery was so early that a discoverer could not be determined HOW WAS IT EXTRACTED The first step of the process of extracting gold is that is it mined from the earth the extraction site can either be underground or at an open ndash pit There are numerous ways you can extract gold but the most popular and simple manual method is called Panning Wide and shallow pans are filled with the sand and gravel that may contain gold then water is added and the panscontaining the gold are shaken causing gold and the other metals to separate and since gold is a much denser metal than rock it settles to the bottom of the pan Fast and is removed from steam beds often at the bend of a stream or a bedrock bed of the stream The weight of gold causes it to separate out of The water flow This type of gold that is found in streams are called placer depositsRELATIONSHIP Gold was found such a long time ago it was used even around during the early times of Christ from this we can conclude that gold is not reactive at all it is even one of the firsts metals on the reactivity series it doesnrsquot react with anything And since it is one of the first metals found it is not reactive because the earlier metals are found means the closer they were to the earth therefore easier to find and metals close to the earth are less reactiveUSES OF THE METAL The main common use for Gold is making Jewelry 78 is sent to factories to manufacture jewelry it is also used to make a wide range of electronic products and equipment eg computers telephones home appliances building components and many more It was used as a medium of exchange or money It is also used as a alloy with other metals because of gold beneficial and useful properties there are countless numbers of uses for it

GOLDDESCRIPTION Gold is shiny is golden color its quite heavy resistant to corrosion a good conductor of electricity its ductile and malleable and It can withstand very high temperatures

LEADDISCOVERY DATE 6400 BCWHO DISCOVERED IT - HOW WAS IT EXTRACTED Lead is usually found in ore with zinc silver and copper and is extractedtogether with these metals Most ores contain less than 10 of Lead The main lead mineral is the sulphide ore Galena which contains 866 lead (wwwWikipediacom) There are a few steps to extract Lead and the first is concentration The ore is concentrated by the froth floatation process In this process lead sulphide ore is wetted by Pine oil where impurities are wetted by water The second step is Smelting Smelting takes place in a Reverberate furnace The concentrated ore is at a moderate temperature The temperature is controlled by how much air supply is given During roasting the sulphide ore galena is partly oxidized to lead monoxide and partly to lead sulphate2PbS + 3O2 rarr 2 PbO + 2SO2

PbS + 2O2 rarr PbSO4

More of galena is then added The temperature is raised therefore reducing air supply Lead sulphide reacts with the Two oxidised products giving leadPbS+2PbO rarr 3Pb+SO

2PbS+PbSO4 rarr 2Pb+2SO2

During this process the roasting and smelting of the Lead ore are carried out in the same furnace but at two different temperatures About 90 of lead is obtained as metal the rest passes into slag Lead is recovered from the slag by heating with lime and powdered coke

LEADRELATIONSHIP Lead reacts with acids and with oxygen When Lead is exposed to air it turns grey Lead is quite reactive it is slightly below the middle of the reactivity series And from the date is was discoveredyou can conclude that lead is not very reactive Because more reactive metals are found earlier because they are nearer to the surface of the earth and the more reactive metals are found deeper within the earth As compared to aluminum (year 1825) lead was found 4575 years before Aluminum and aluminum is much more reactive than lead it is higher in the reactivity series USES OF THE METAL Lead has a number of important uses that interfere with our daily lives eg It is used to make the lead- acid battery used in cars in PVC pipes which coat electrical wires it is used to shield people from radiation from x-ray rooms an electrode in the process of electrolysis and gutters

LEADDESCRIPTION Lead is is a heavy soft metal that is a solid at normal atmospheric and crustal pressures (wwwenotescom) It tarnishes and turn dull when it becomes exposed to oxygen lead is not a good conductor of electricity heat sound or other pressure vibrations And it is ductile and malleable

ConclusionThe question was ldquoto find the relationship between the date of discovery of a metal and its reactivityrdquo And from my research you can conclude that the relationship between the discovery date of a metal and its reactivity is that the earlier a metal is found the less reactive It is because less reactive metals are found closer to the earths surface therefore making it easier to dig up and find or extract eg gold it is least reactive metal on the reactivity series and is was found such a long time ago that researchers cannot even verify who discovered it and when And the more reactive metals are found deeper within the earth therefore these metals were discovered much later eg Sodium was found in year 1807 not so long ago and this metal is highly reactive so reactive it even reacts with water in order to store this metal it has to be stored under oil
