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.)

The chemical element nickel is classed as a transition metal. In the 1750s nickel was discovered to be an element by Axel Cronstedt.

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.

Workers who have breathed very large amounts of nickel compounds have developed chronic bronchitis and lung and nasal cancers.

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.

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).

Male plugs are designed to go on the end of a SPT wire of the correct matching size. Male plugs are polarized and it is important that you install the wire correctly to match the polarity of the wire and plug. The two vampire teeth are designed to each pierce one wire when they are installed. You should look at the plug to identify which tooth is which.

In 2013 a group buy took place that offered a Fused Male/Female Plug similar to what is found on traditional incandescent light strings. This new plug has built in fuses. These plugs do not have traditional Vampire teeth, but instead are attached to the wire by either crimping or soldering. They came in a Male/Female Plug with a 3A fuse and a Male Plug with a 5A fuse.

Vampire plugs get their name from the insulation piercing teeth that they have. They are designed to be used on SPT wire and allow a fast and easy way to terminate a wire. Vampire Plugs come in different shapes and functions. They come in three basic colors, Black, Green and White. The common Male Plug and Female Socket made by Zing Ear are rated for 8A @ 125VAC. Confirm the ratings and wire size by reading the printing on the item or asking your vendor. IMPORTANT: IT IS CRITICAL THAT YOU USE THE CORRECT VAMPIRE PLUG OR SOCKET THAT MATCHES YOUR WIRE TYPE! PLUGS AND SOCKETS ARE MADE FOR SPECIFIC WIRES TYPES, THEY ARE NOT UNIVERSAL. SPT-1 SOCKETS AND PLUGS SHOULD NOT BE USED WITH SPT-2 WIRE AND SPT-2 SOCKETS AND PLUGS SHOULD NOT BE USED WITH SPT-1 WIRE.

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.

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%

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.

thank you this helped me so much im doing a poster in school about nickel and i got my poster all done with this website

In the early twentieth century, Ludwig Mond patented a process using nickel carbonyl to purify nickel. This process is still used today.

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.

Tubing made from a copper-nickel alloy is used in desalination plants. This alloy is naturally resistant to corrosion by seawater and to biofouling.

SPT Wire,Vampire Sockets and Plugs are frequently available at preseason discounts during January and February from most vendors.

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.

Female sockets are designed to go on the end of a SPT wire of the correct matching size. Female sockets are polarized and it is important that you install the wire correctly to match the polarity of the wire and plug. The two vampire teeth are designed to each pierce one wire when they are installed. You should look at the socket to identify which tooth is which.

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.

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. ?

Artifacts made from metallic meteorites have been found dating from as early as 5000 BC – for example beads in graves in Egypt.(1)

Female inline sockets are designed to go in the middle of a SPT wire of the correct matching size. They look similar to regular Female Sockets but the end is missing on both sides so the wire can go thru both sides. Some people1, 2 modify regular Female Sockets to make them Inline. Female sockets are polarized and it is important that you install the wire correctly to match the polarity of the wire and plug. The two vampire teeth are designed to each pierce one wire when they are installed. You should look at the socket to identify which tooth is which.

C7 or C9 sockets are designed to go in the middle of a SPT wire of the correct matching size. C7 or C9 sockets are polarized and it is important that you install the wire correctly to match the polarity of the wire and plug. The two vampire teeth are designed to each pierce one wire when they are installed. You should look at the socket to identify which tooth is which.

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.
