Usesof nickel

Resembling the properties of its periodic table neighbors – iron and cobalt – the nickel metal also possesses strong magnetic and anti-corrosive properties. Namely, it’s ferromagnetic at room temperature and resists corrosion even at high temperatures.

After conducting numerous chemical experiments, Cronstedt observed that the new substance has strong magnetic properties which did not correspond to the weak magnetic strength of copper. This led him to the conclusion that he had discovered a new chemical element.

Among the 26 radioactive isotopes that have been identified so far, the 63Ni form has the longest half-life (100.1 years).

The pure, elemental form of nickel was isolated in 1775 by the Swedish mineralogist and chemist Torbern Bergman (1735 – 1784). Namely, Bergman was the first scientist who succeeded in isolating the pure nickel metal from what other scientists thought was an alloy of cobalt, arsenic, iron, and copper. By this, he also confirmed the chemical properties of the new element, which classified element 28 as a new member of Mendeleev’s periodic table.

Prolonged skin contact with nickel or occupational exposure to this chemical may trigger a nickel allergy if accumulated in high levels in the body. This adverse health effect is characterized by an itchy rash from jewelry made with nickel, for example, or from contact with coins, zippers, cellphones, etc.

While the aforementioned symptoms are similar to the way pneumonia manifests, nickel poisoning may quickly lead to fatal consequences.

Apart from the most common symptoms of nickel allergy, such as skin rash and itching (allergic contact dermatitis), the affected individual may also experience the following symptoms:

According to the National Cancer Institute, nickel compounds have been classified as carcinogenic substances. Nickel exposure can occur by smoking cigarettes, consumption of food, and drinking water containing high nickel concentrations, as well as by inhalation of nickel-contaminated air or nickel dust. Nickel and nickel compounds are also labeled as skin sensitizers, meaning they can lead to skin irritation, eczema, as well as to allergic contact dermatitis.

There are 32 isotopes of nickel, with atomic mass ranging from 48Ni to 80Ni. The naturally occurring nickel is made up of five stable isotopes: nickel-58, nickel-60, nickel-61, nickel-62, and nickel-64. With 68.077% of natural abundance, nickel-58 is the most abundant form of this chemical element.

Who discoverednickel

The human body needs minuscule amounts of nickel as a trace element. Most of the food we consume contains some amount of nickel since this element can be naturally found in soil, air, and waters. For this reason, plant-based food tends to contain higher amounts of nickel than meat.

Light Reflective Value (LRV) measures the amount of visible and usable light that reflects from (or absorbs into) a painted surface. The scale is black/zero to white/100.

Since nickel mainly occurs in Earth’s iron-nickel core, it’s relatively inaccessible. The organic substances that also occur in the deeper layer of Earth, such as oil and coal, absorb nickel in large amounts. Element 28 can be frequently traced along with sulphur and arsenic in nickel glance, with arsenic in niccolite, and with sulphur in millerite. The largest nickel-mining areas in the world are located in Canada, Australia, South Africa, Cuba, Indonesia, New Caledonia in the Pacific, and Russia.

When nickel becomes a part of a chemical compound, it typically adopts the oxidation state of +2. As a result of the extreme similarity between the ionic radii of the cations, many nickel salts nickel(II) are isomorphous with the magnesium salts. All nickel compounds (especially the salts) are highly toxic.

Some sources claim even earlier use of nickel by the ancient civilizations. According to a survey published by the American Journal of Archeology, nickel beads have been found in graves located in Egypt, believed to have been made from metallic meteorites.

Where isnickelfound

Classified as a transition metal, this chemical is most often obtained from iron/nickel sulfides, such as pentlandite, garnierite, and nickeliferous limonite. For commercial purposes, the nickel carbonyl process is used to purify nickel extracted from nickel ores, such as laterites and magmatic sulfide deposits.

During the 1600s, a copper-resembling dark red ore was traced by copper miners in Saxony, Germany. Due to their inability to isolate the metal substance from the ore, the miners thought that those types of ores were possessed by the goblin that made it hard for them to obtain the metal. Due to this, they labeled the substance “kupfernickel”, i.e. “goblin’s copper”.

Light Reflective Value (LRV) measures the amount of visible and usable light that reflects from (or absorbs into) a painted surface. The scale is black/zero to white/100.

According to NIOSH, the refinery workers in nickel processing plants, jewelry and pawnshop workers, as well as the workers who come into contact with nickel releasing surfaces are in the greatest danger of acquiring nickel allergy as an occupational disease. The prolonged exposure or high uptake of this chemical element in all its forms may also increase the risk of cancer in these workers.

Nickel is a chemical element with the atomic number 28 in the periodic table. It’s found in Earth’s crust with an abundance of 84 parts per million by weight. Being a member of the transition metals family of the periodic table, this divalent silvery-white metallic element has strong corrosion resistance and moderately strong ferromagnetic properties.

Cronstedt himself named the newly discovered element ‘nickel’, which is short from the term ‘kupfernickel’ – the ore from which he succeeded to obtain the new substance.

Nickel allergy can often be triggered by a high uptake of foods rich in this trace mineral or drinking water. The list of foods containing high nickel concentrations include:

Physicalproperties of nickel

Hundreds of millions of years ago, our planet has been ‘showered’ with meteors containing iron. According to Washington University at St. Louis, almost 95% of the meteors have been composed of the iron-nickel (FeNi) metal compound. Nowadays, this chemical element naturally occurs in air, soil, and waters. It’s an essential trace element for some animals and plants, while our body requires an extremely small quantity of it.

Nickel can enter the atmosphere from the exhaust gasses and waste of the refining plants, as well as from power plants by coal or oil-burning. Once the nickel particles are released into the air, they attach to the dust particles that are already in the air. After some time, the nickel dust falls to the ground by itself or mixed with precipitation. In this way, nickel enters and contaminates both the soil and the surface waters.

Nickel is the first material of choice for many industries, mainly because of its ferromagnetic and anti-corrosive properties. The automotive, electronic, and construction industries make wide use of nickel as a means of insulation and protection. The other nickel applications in the everyday life are given in the following instances:

With the periodic table symbol Ni, atomic number 28, atomic mass of 58.693 g.mol-1, and electron configuration [Ar]3d84s2, nickel is a hard and ductile metal with a silvery-white color. It reaches its boiling point at 2913°C, 5275°F, 3186 K, while the melting point is achieved at 1455°C, 2651°F, 1728 K. This member of the transition metals group in the periodic table has an electronegativity of 1.91 according to Pauling, whereas the atomic radius according to van der Waals is 163 pm.

In 1751, the Swedish mineralogist and chemist Axel Fredrik Cronstedt (1722 – 1765) focused his chemical investigations on a new mineral sample obtained from a mine in Los, Hälsingland, Sweden. It was the same type of ore that puzzled the copper miners from Saxony – the “kupfernickel” (i.e. nickel arsenide, NiAs). Due to the reddish-golden streak in the ore, Cronstedt believed that there really might be some copper in the compound.

Since nickel has been brought to Earth by the meteorites, we can freely say that this chemical element has been around for ages. The first evidence of this silvery metal with a slightly golden tinge dates from 200 BC. Namely, a zinc-nickel alloy called ‘pai-t’ung’ (white copper) has been widely used in ancient China for manufacturing various artifacts that did not rust. For the Peruvians, nickel was “a type of silver”.
