What is Cobalts chemical name? cobalt (Co), chemical element, ferromagnetic metal of Group 9 (VIIIb) of the periodic table, used especially for heat-resistant and magnetic alloys.
What is cobalt? Cobalt is commonly used as a binding agent in the manufacture of ‘hard’ metals with increased wear resistance such as drills and cutting tools. It is also found in: Jewellery [see Jewellery allergy] Metal household items (eg, cutlery, zippers, coins, keys,)
What are Cobalts chemical properties? Cobalt is a hard ferromagnetic, silver-white, hard, lustrous, brittle element. The element is active chemically, forming many compounds. Cobalt is stable in air and unaffected by water, but is slowly attacked by dilute acids.
Why is it called Cobalt? The name cobalt comes from the German word for goblin, “kobold.” Medieval miners considered this element troublesome because its ore released toxic vapors when smelted, according to the U.S. Geological Survey (USGS). Cobalt is an essential trace nutrient for health. Cobalt.
Cobalt color is often referred to as elegant and highly saturated shade of blue. Sometimes it is mistaken for cornflower blue, sapphire and indigo. Cobalt HEX code is #19247c, in RAL system it’s 5013. Its name originates in cobalt – a grey-blue colored chemical element in the group of metals.
Cobalt is also used to make airbags in automobiles; catalysts for the petroleum and chemical industries; cemented carbides (also called hardmetals) and diamond tools; corrosion- and wear-resistant alloys; drying agents for paints, varnishes, and inks; dyes and pigments; ground coats for porcelain enamels; high-speed
Cobalt forms part of the structure of vitamin B12. Vitamin B12 has several important functions including making red blood cells and releasing energy from the food you eat.
Cobalt is an essential raw material for superalloy, cemented carbide, diamond tool, batteries, anticorrosive and magnetic materials. It is widely applied in fields including aerospace, electronic appliances, machinery manufacturing, automobiles, chemical industry, agriculture, ceramics, etc.
Cobalt is also an essential trace element for humans, and is found at the centre of vitamin B12 and a range of other co-enzymes called cobalamins. Even though the body contains only 2–5 mg of vitamin B12, its involvement in the production of red blood cells means it is vital to life.
The nitrogen family includes the following compounds: nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).
Cobalt is somewhat of a reactive element. It combines with oxygen in the air, but does not catch on fire and burn unless it is in powder form. Cobalt has the ability to react with most acids to produce hydrogen gas.
Cobalt is the first metal with a recorded discoverer. Swedish chemist Georg Brandt (1694-1768) first isolated it in 1735. His research proved that the blue color came from the Cobalt. 4.
The element cobalt’s name comes from the German word kobold, meaning goblin or evil spirit. It was named by miners in 16th century Saxony who thought they had found deposits of silver but had actually found cobalt arsenide.
It may cause nausea and vomiting. However, absorbing a large amount of cobalt over longer periods of time can lead to serious health problems, such as: Cardiomyopathy (a problem where your heart becomes big and floppy and has problems pumping blood) Deafness.
Cobalt, is symbol Co on the periodic table with an atomic weight of 27. While in it’s natural, raw state it’s a somewhat burnished silver colour, it is famously known for producing vibrant blues in pigments. Imitation colours are typically known as “hues”, as in Cobalt Blue = real thing, Cobalt Blue Hue = imitation.
When cobalt salts and aluminum oxide are mixed, you get a beautiful shade of blue. The color cobalt or cobalt blue is a medium blue, lighter than navy but bluer than the lighter sky blue color. With the addition of varying amounts of other metals or minerals, cobalt can be more magenta or more purple.
Cobalt is a ferromagnetic metal with a specific gravity of 8.9. The Curie temperature is 1,115 °C (2,039 °F) and the magnetic moment is 1.6–1.7 Bohr magnetons per atom. Cobalt has a relative permeability two-thirds that of iron.
The Democratic Republic of the Congo has the largest cobalt reserves in the world, at some 3.6 million metric tons as of 2020. As the total global cobalt reserves amount to 7.1 million metric tons, this means that the DR Congo’s cobalt reserves account for nearly half of the world’s reserves of the metal.
In 2009, Chevrolet launched the Cobalt’s eventual successor, the Chevrolet Cruze (based on the new Delta II platform), in Europe, with launches in other markets (including the US) following in 2010. The Cobalt ended production on .
Umpteen dietary resources contain ample volumes of cobalt, namely cruciferous vegetables like cabbage, lettuce, whole grain cereals such as barley, oats, besides dairy produce, animal meat, fish, oysters and eggs.
The organic form of cobalt is present in green parts of plants, fish, cereals, and water [8, 9]. In the human body this element is present in amounts from 1 to 2 mg: we can find it in the heart, liver, kidney, and spleen, and considerably smaller quantities in the pancreas, brain, and serum [10, 11].
Thus, the correct answer is B12.
The cobalt content of coffee was found to be considerably higher than that of tea. The content of 5 teas, averaged, was 0,20 μg/g tea and that of 7 coffees was 0,93 μg/g coffee, the average of 3 different methods, each of which averaged 0,75, 0,89 and 1,14 μ/g coffee.
It can also replace zinc in some biochemical reactions. Cobalt is also part of the biotin-dependent Krebs cycle.
The group 17 elements include fluorine(F), chlorine(Cl), bromine(Br), iodine(I) and astatine(At) from the top to the bottom. They are called “halogens” because they give salts when they react with metals.
