Importance of Metals

A metallic element is defined as an opaque vivid element which possesses properties such as malleability and ductility. Malleable meaning that they hind end be hammered into shapes and ductile meaning they can be gaunt into wires. They ar also very strong and posses graduate(prenominal) tensile forcefulness and are good conductors of heat and electricity. Metals are shiny, and also have high densities. Metals are a very valuable and significant part of chemistry. However, their brilliance is non just limited to chemistry they are also utilise in our daily lives.We may not realize this but without metals we would not be able to continue with our daily routines as metals play an important role. Metals are used in the do of household conveniences corresponding ovens, dishes, cutlery etc. they are also used in transference such as cars, buses, trucks, trains. Computers and electronic devices are also do up of metals. Electrical power production and distribution, even most o f the construction is made out of steel which is an alloy a mixture of metals such as iron and carbon.And it is because of the specific properties of metals, which allow them to be used in the making of such objects. Although we see metals almost everywhere we go, metals are not install easily. In fact, most of the metals are present in the hides crust but when found in the earth these are ofttimes mixed with other substances. The rocks in the earths crust are a mixture of substances, these rocks from which a metal can be extracted from is cognize as an ore. The regularity used to extract metals from ores depends on the reactivity of that metal.Some neutral metals can even be found in the native state, similar gold. On the other hand, most metals are too reactive to pull through on their own like atomic number 13, which has to be extracted exploitation a method called electrolysis. And some moderately reactive metals that are in the middle of the reactivity series can be e xtracted using reduction of oxides like iron. atomic number 79 is not found in a mixture or combine state but is also quite rare. Gold is extracted by mining.Gold is a very demanding and expensive metal, the 2nd most expensive after platinum. The metal aluminium is extracted from its one aluminium oxide which is also known as bauxite which is principally aluminium oxide (Al2O3)It is also the most abundant metal in the earths crust but is never found separately, only in its bauxite. Aluminum being a reactive metal has to be extracted using electrolysis. The process of electrolysis requires massive amount of energy and therefore making aluminium expensive to produce.
