Ni is a hard , silver - clean metal whose strength , ductility and resistor to estrus and corroding make it extremely useful for the development of a wide of the mark variety show of materials — from conducting wire to coin to military equipment .
This extremely useful metal is No . 28 in theperiodic board of the elements , between the component cobalt and copper color . atomic number 28 is a fairly near conductor of electricity and heat and is one of only four elements ( Co , atomic number 26 , nickel note and gadolinium ) that are ferromagnetic ( magnetise easily ) at room temperature . Nickel is a transition alloy , think it has valence electrons in two shells instead of one , let it to form several different oxidation state .

Discovery
The breakthrough of nickel note ore in seventeenth - century Europe is a tale of false identity and superstition . In the 1600s , German miners searching for copper in the Ore Mountains come upon a antecedently unknown nickel ore ( know today as atomic number 28 arsenide or niccolite ) — a pale chocolate-brown - crimson rock of nickel and arsenous oxide . think they ’d get wind another copper ore , the miners undertake to draw out the copper , but , of course , the rocks failed to produce . The defeated miners blame Nickel , a mischievous demon in German mythology , for play a prank on them and start calling the orekupfernickel , translated as " atomic number 29 demon . "
About a 100 by and by , in 1751 , the Swedish alchemist Baron Axel Fredrik Cronstedt try heating kupfernickel with charcoal and plant that its various properties — such as being blanched and charismatic — clearly let out that it was n’t Cu . Cronstedt is accredit as the first somebody to draw out nickel and sequestrate it as a new factor . He dropped the name " kupfer " and scream the Modern elementnickel .
Where on Earth?
Ni is the fifth most abundant element on Earth . However , it is 100 time more concentrated below the Earth ’s crust than in it , according toChemicool . In fact , nickel is believed to be the 2d most abundant element in the Earth ’s inner core , with atomic number 26 being the first by a large margin .
atomic number 28 is typically found in two character of deposits : laterite deposit , which are the event of intensive weathering of surface atomic number 28 - fertile rock ‘n’ roll , and magmatic sulphide deposits . Ni can also be regain in manganese nodules and Earth’s crust on the thick sea floor , but presently these are not being mined , according toGeology.com . The independent mineral sources of Ni are limonite , garnierite and pentlandite .
In 1848 , Norway became the first large - scale nickel note smelting internet site . Here they used a type of nickel ore recognize as pyrrhotite . In 1883 , large deposits of atomic number 28 were strike in the Sudbury Basin in Canada , which is where about 30 percent of the world ’s nickel is mined today . It is believed that this large depositary of nickel is due to an ancient meteor impact . More nickel note was see in Russia and South Africa in the former 1900s , further allow for nickel note to take a potent place in industry .

Just the facts
Super metal
Few thing are made of virgin nickel . Instead , Ni run to play a supportive and stabilize role in industry materials ; it is usually combined with other metals to produce stronger , shinier and more undestroyable product . nickel note is commonly used as a protective outer coating for softer metals .
Because of its ability to withstand extremely mellow temperature , nickel is the metal of choice for making superalloys — metal combos that are sleep with for great specialty as well as resistance to heat energy , corrosion and oxidation . In fact , approximately 65 percent of nickel is used to manufacture unsullied brand and another 20 per centum is used to make other steel and non - cast-iron alloys , admit highly - specialized military , aerospace and industrial uses , according to theNickel Institute . About 9 per centum is used in plating and 6 per centum goes toward other character of program , such as coins , batteries and electronics .
Money talks
Since nickel is such a uncompromising and corroding - resistant fabric , it is an splendid metallic element for coin - making . The first coin to let in the metal atomic number 28 was the one - penny piece Flying Eagle , an American coin made of 12 percent nickel and 88 pct cop . This coin , which was also the first to go by the name " nickel , " only circulate two years , between 1857 - 1858 .
The five - cent nickel was introduced a few years later in 1866 just after the Civil War come to an oddment . Prior to the war , most coin were still made of gold and silver , which gave them intrinsic time value . As rumors of war began to spread , people started hive up these valuable coins , causing the economy to take a nosedive . To compensate for the lack of coins , people started trade stamps and notes that had been issued by money box and shop class . Even Union soldier were being paid with notes by the politics .
In the lag , industrialist Joseph Wharton had bought several nickel note mines in the other year of the warfare . Nickel was a much - require metal during the warfare as it was used to aid make military equipment . Once the war finish , however , there was a nimiety of nickel , and Wharton probably wondered what he was going to do with all of his nickel . He urged legislators to start micturate more coins with nickel note . After all , people would be a lot less likely to hoard this less valuable metal .
The lawmaker listened , and in 1866 , the American administration minted 15 million 5 - cent coin made of 75 per centum copper and 25 percentage nickel . Nickels deluge the economy and became the most prominent coin in the after - warfare geezerhood .
In the United States , nickels , dimes , quarters and half - dollars are still made of a copper - nickel alloy . The nickel coin , quite competently , contain the most nickel at 25 percent , while the other coin are 8.33 percent atomic number 28 .
Who knew?
Magnetism
Ni is one of only four metals that are ferromagnetic , meaning they are attracted to magnets and are magnetized themselves . The others are iron , cobalt and atomic number 64 . Alnico magnets — a combination of aluminum ( Al ) , nickel ( Ni ) and cobalt ( carbon monoxide gas ) — are very strong permanent attractor that retain their magnetism even when ignite until they radiate red , according to Chemicool .
Mu - alloy is a piano magnetic admixture of approximately 80 percent nickel and 20 percent atomic number 26 ( and a bolt of Mo ) . Mu - metal has very in high spirits permeableness , which allow it to harbour sensitive electronic equipment against static or low - frequency magnetic field . If you come out Mu - metal between a magnet and metal , the common magnet in reality disappears .
Toxicity
atomic number 28 is an substantive element for healthy plant lifetime , and vestige amounts are naturally find in most vegetables , yield , nuts and in more or less greater amounts in cocoa and wine-coloured , according to the Nickel Institute .
But like most metals , nickel has a dark side when too much enter the human body . When large total of nickel — which is a known carcinogenic — accumulate in the soil , air , or our food and piddle supply , there are risks of toxicity .
People who put to work in jobs of Ni refining , electroplating and welding are at the keen risk for wellness problem . Workers who suspire in traces of nickel detritus are at an increased peril for lung cancer , fibrosis and other ailments .
In 2012 , 25 nickel - plating workers in Egypt were given liver function tests . Theresultsoverwhelmingly establish inadequate liver function among the nickel note workers compared to the dominance group . Anotherstudyin Saudi Arabia also exposed the toxic effects of nickel note pic on the lungs and airway , but the researchers also come upon an interesting fact : take dietary curcumin , the active factor in the spiceturmeric , was linked to a significant reduction in toxicity and oxidative strain .
