In frustration, they had named it ‘kupfernickel’ which could be translated as ‘goblin’s copper’ because clearly, from the miners’ point of view at any rate, there were goblins or little imps at work, preventing them extracting the copper.

Tubing made from a copper-nickel alloy is used in desalination plants. This alloy is naturally resistant to corrosion by seawater and to biofouling.
In the 1600s, a dark red ore, often with a green coating, had been a source of irritation for copper miners in Saxony, Germany. They believed the dark red substance was an ore of copper, but they had been unable to extract any copper from it.
The chemical element nickel is classed as a transition metal. In the 1750s nickel was discovered to be an element by Axel Cronstedt.
Source: Nickel occurs occasionally free in nature but is mainly found in ores. Its chief ores are pentlandite and pyrrhotite (nickel-iron sulfides), garnierite (nickel-magnesium silicate), millerite (nickel sulfide) and niccolite (nickel arsenic).

Nickel is also used in batteries – for example NiCd (nickel-cadmium) and Ni-MH (nickel-metal hydride) rechargeable batteries – and in magnets.

In cobalt’s case, miners mistakenly thought the ore contained silver, and called the ore kobold in frustration at the wicked goblins who they believed were preventing them getting silver from the ore.

Isotopes: Nickel has 23 isotopes whose half-lives are known, with mass numbers 52 to 76. Naturally occurring nickel is a mixture of its five stable isotopes and they are found in the percentages shown: 58Ni (68.1%), 60Ni (26.2%), 61Ni (1.1%), 62Ni (3.6%) and 64Ni (0.9%). The most abundant isotope is 58Ni at 68.1%

After finding that its chemical reactions were not what he would have expected from a copper compound, he heated kupfernickel with charcoal to yield a hard, white metal, whose color alone showed it could not be copper. Its properties, including its magnetism, led him to conclude that he had isolated a new metallic element.

Hi Nataiya, Nickel with 31 neutrons is radioactive, and there isn’t much of it anywhere! Nickel’s atoms can have as few as 24 neutrons to as many as 48 neutrons. 68.1% of nickel atoms have 30 neutrons. ?
In the early twentieth century, Ludwig Mond patented a process using nickel carbonyl to purify nickel. This process is still used today.

Workers who have breathed very large amounts of nickel compounds have developed chronic bronchitis and lung and nasal cancers.
Carbide drills provide faster cutting rates, longer tool life, better positional and dimensional accuracy and improved surface finish.
The names of both elements have their origins in the frustrations of miners caused by metal-arsenic ores: nickel arsenide and cobalt arsenide. Cobalt’s name is derived from the German ‘kobold’ meaning ‘goblin’ – a close relative of the creature from which nickel’s name was derived.
Between 1751 and 1754, the Swedish chemist Axel Cronstedt carried out a number of experiments to determine the true nature of kupfernickel. (We now know that kupfernickel is nickel arsenide, NiAs.)

Nickel is taken from its ores by roasting and reduction processes which produce a metal of over 75% purity. The Mond process is then used to purify the nickel further.

Miners in Germany believed little fellows like this one had stopped them extracting copper and silver from nickel and cobalt arsenides. Fortunately George Brandt and Axel Cronstedt took a more scientific approach to the problem and discovered two new elements. Image by JNL.

There is a satisfying symmetry in this discovery. Cronstedt was a pupil of George Brandt, who had discovered cobalt, which sits immediately to the left of nickel in the periodic table.

The first meteorite ever photographed on another planet. In 2005 NASA’s Mars rover Opportunity used spectrometers to discover that this basketball-size meteorite was mainly iron and nickel. Image by NASA/JPL/Cornell.
Artifacts made from metallic meteorites have been found dating from as early as 5000 BC – for example beads in graves in Egypt.(1)
Nickel and its compounds are considered to be carcinogenic. Approximately 10 to 20 percent of people are sensitive to nickel. Repeated contact with it leads to skin complaints (dermatitis). Such people should avoid contact with nickel, which can be found in jewelry.
