The biological role of nickel is uncertain. It can affect the growth of plants and has been shown to be essential to some species. Some nickel compounds can cause cancer if the dust is inhaled, and some people are allergic to contact with the metal. Nickel cannot be avoided completely. We take in nickel compounds with our diet.
It is an essential element for some beans, such as the navy bean that is used for baked beans. Natural abundance. It is also found in other minerals, including garnierite. A substantial amount of the nickel on Earth arrived with meteorites. One of these landed in the region near Ontario, Canada, hundreds of millions of years ago.
Help text not available for this section currently. Elements and Periodic Table History. Meteorites contain both iron and nickel, and earlier ages used them as a superior form of iron. Because the metal did not rust, it was regarded by the natives of Peru as a kind of silver. Some even reached Europe. He thought it might contain copper but what he extracted was a new metal which he announced and named nickel in Many chemists thought it was an alloy of cobalt, arsenic, iron and copper — these elements were present as trace contaminants.
It was not until that pure nickel was produced by Torbern Bergman and this confirmed its elemental nature. Atomic data. Glossary Common oxidation states The oxidation state of an atom is a measure of the degree of oxidation of an atom.

Listen to Nickel Podcast Transcript :. You're listening to Chemistry in its element brought to you by Chemistry World , the magazine of the Royal Society of Chemistry. Several years ago, I went with a friend to a small exhibition at London's National Gallery.
It was a rare opportunity to see the masterpieces from the Doria Pamphilii gallery in Rome. The centrepiece was the famous portrait of Pope Innocent X by Velazquez, a spectacular snapshot of one of the most powerful men of his day, a tough-looking character in a gilded throne, sporting a neat goatee and a fierce and uncompromising glint in his eye. The pictures were so ugly and brutal that I instinctively blinked and looked away, upwards. Unexpectedly, my eyes fell on a set of golden letters across the top of the doorway.
I giggled and my friend said to me, 'what's so funny? These pictures are just awful. He didn't. Nickel had been known for some time before that - it had been used in China and Peru to make a kind of steel.
But it wasn't until the 19th century that two Swedish chemists, Cronstedt and Bergmann between them established that it was an element.
It was named nickel after one of its ores, a reddish material that German miners called kupfernickel - St Nicholas's copper. Wasn't there some problem with nickel jewellery? Nickel has long been used in alloys and to plate other metals - the nickel provides a tough resistant and shiny coating that protects the object from corrosion. Nickel is a bit more subdued. But the problem is that in contact with the skin, as in jewellery, the tiny amounts of nickel that dissolves in the sweat of the wearer was enough to cause skin reactions in some people and the using nickel turned out not to be a great idea.
And he had a problem - he was passing carbon monoxide gas through nickel valves and these kept failing and leaking. What Mond and his assistant Langer discovered was something remarkable - that his valves were corroding because the metal reacted with carbon monoxide, to make a compound called nickel carbonyl. Because it's so volatile, you need to be really careful when you handle it since if you inhale it, it will decompose releasing poisonous carbon monoxide and dumping metallic nickel into your lungs.
So it's very dangerous indeed. But in a way, that's the beauty of it: nickel carbonyl is incredibly fragile. If you heat it up it shakes itself to pieces, and you get both the nickel and the carbon monoxide back. So what Mond had was a deliciously simple way to separate and purify nickel from any other metal. And what is more, he could recycle the carbon monoxide. He was also a pretty savvy business man. He patented his process and set up in business to sell the purest nickel at prices far lower than anyone else.
He made an absolute fortune, and then steadily expanded into other areas of chemistry. His firm would eventually form the core of Imperial Chemical Industries, ICI, the conglomerate set up to defend British interests against, ironically, the onslaught of the burgeoning German chemicals industry.
In the s another German chemist named Wilke developed nickel compounds as cheap and simple catalysts for the petrochemicals industry to clip together small carbon molecules. It's also used in all sorts of alloys. There's Invar which is a kind of metallic pyrex, that doesn't expand or contract when you change the temperature. There's Monel, a steel so corrosion resistant that it will withstand even fluorine, which eats its way through just about anything. And there's the really weird memory metal, an alloy that no matter how much you twist and bend it, remembers its original shape and returns to it.
And then there's superalloys made of nickel and aluminium with a dab of boron that are extremely light and actually get tougher as you heat them - so they're used in aircraft and rocket turbines.
I could see I was going a bit too far. We turned back to the Pope. No doubt you're expecting me to say that it all ended happily. It didn't, and I haven't seen her in years. But weirdly enough, every time I think of nickel, I think of her. And the filthy look the Pope gave me.
So superalloys, relationships and the pope, what diverse chemical thoughts and stories nickel provokes. Now next week the discovery of xenon. The story of xenon begins in when Lord Rayleigh and William Ramsay were investigating why nitrogen extracted from chemical compounds is about one-half per cent lighter than nitrogen extracted from the air - an observation first made by Henry Cavendish years earlier.
Ramsay found that after atmospheric nitrogen has reacted with hot magnesium metal, a tiny proportion of a heavier and even less reactive gas is left over. They named this gas argon from the Greek for lazy or inactive to reflect its extreme inertness. The problem was, where did this new element fit into Mendeleev's periodic table of the elements? There were no other known elements that it resembled which led them to suspect that there was a whole family of elements yet to be discovered.
Remarkably, this turned out to be the case. And to hear how this story paned out, leading to the discovery of a new family of elements as well as xenon that would go on to light our roads and propel spaceships join Cambridge University's Peter Wothers in next week's Chemistry in its element. The researchers used RIBF to smash U particles on a target to induce an artificial fission splitting reaction.
Instruments at RIBF also allowed them to probe the sample they created. To do this the researchers observed gamma rays a kind of radiation from their excited 78Ni sample and recorded their characteristics. In this case, Taniuchi and colleagues looked for a telltale signature in the gamma-ray data to confirm their hypothesis.
You need sufficient data to identify the doubly magic characteristic and we struggled to get that despite access to the world-leading accelerator facility, RIBF," said Taniuchi.
Results suggest 78Ni is doubly magic, but also that the magic nature suddenly disappears in isotopes beyond 78Ni. You might wonder what is so important about 78Ni in the first place. Its existence may actually be pivotal to understanding the origin of matter. Life may not have been possible without it. We know that many are made in supernova explosions -- the death throes of giant stars -- or even in collisions between neutron stars," explained Taniuchi.
As a consequence of our discovery, researchers exploring this fascinating field can create better ideas about the origin of matter. Journal article R. Taniuchi, S. Momiyama, M. Niikura, T. Otsuka, H.
