Cobalt History Essay Example

it forms insoluble precipitates known as cobalt sulfine. Generally, cobalt is not readily available in the environment. Nevertheless, plants and animals can absorb unbound cobalt particles if they are not bound to soil or sediment particles, leading to accumulation. As a result, cobalt becomes part of both human and marine life cycles.

While liquid cobalt can be more dangerous than mercury in large amounts, it has several benefits for humans. It is a vital part of vitamin B12, which is essential for human health and plays a crucial role. Liquid cobalt is also used to treat anemia in pregnant women by stimulating the production of red blood cells. The daily intake of cobalt can vary and reach up to 1 mg, but most of it passes through the body without being absorbed except for the cobalt found in vitamin B12. However, excessive levels of cobalt can be harmful when inhaled, leading to lung-related issues like asthma and pneumonia, especially among those who work with cobalt.

Cobalt's periodic information can be identified through the abbreviation or symbol Co, its atomic number is 27, and it belongs to period 4 group 9. The precise atomic weight of cobalt is 58.933195 micrograms. In further detail, cobalt has a total of 40 isotopes, of which 1 is stable, 11 are radioactive, and 11 are isomers, resulting in a grand total of 40. Cobalt's electron configuration is [Ar]4s23d7, although its exact meaning is not clear. Nonetheless, it holds significance.

Now, part of this report involves understanding and listing the physical and chemical properties of Cobalt. A few years ago, I conducted a similar project but cannot remember

all the properties currently. Cobalt has the appearance of a hard, brittle metal similar to iron and nickel. Its metallic permeability is around two-thirds that of iron. Over a wide temperature range, cobalt tends to exist as a mixture of two allotropes, although I am unsure about the exact calculations. This transformation happens slowly, leading to significant variation in reported data on cobalt's physical properties. Personally, I believe that cobalt surpasses iron, but that is only my opinion.

I have enjoyed sharing information about cobalt with you, but I have reached the end of my report and have no more information to provide. In conclusion, remember that if you believe cobalt is merely a gum flavor sold at Wal-Mart, reconsider your understanding.
