Selenium

Selenium has an atomic number of 34, which means it has 34 protons. To find the number of neutrons in selenium-80, subtract the atomic number (34) from the isotope number (80). Therefore, selenium-80 would have 46 neutrons (80 - 34).

Yes, selenium is bigger than polonium. Selenium is a nonmetal element with an atomic number of 34 and a larger atomic radius compared to polonium, which is a metalloid element with an atomic number of 84 and a smaller atomic radius.

Selenium is generally considered stable in its elemental form. However, some of its isotopes are unstable and undergo radioactive decay.

Selenium is a mineral, not a vitamin, and can be found in a variety of foods like Brazil nuts, fish, poultry, eggs, and whole grains. It is important for immune function and thyroid health. Supplementing with selenium should be done carefully, as too much can be harmful.

Yes, some people can be allergic to selenium, although it is rare. Symptoms of a selenium allergy may include skin rashes, itching, and difficulty breathing. Consulting with a healthcare provider for proper diagnosis and treatment is recommended.

Selenium was not identified as an element until 1818 because it is a trace element found in a limited number of ores and does not occur in its pure form in nature. Its discovery was also hindered by its similarity to tellurium, another element with similar chemical properties, which made it difficult to separate them. Additionally, advancements in analytical chemistry techniques were necessary for its isolation and identification.

High blood levels of selenium (>100 mcg/dL) can result in a condition called selenosis. Symptoms of selenosis include gastrointestinal upsets, hair loss, white blotchy nails, garlic breath odor, fatigue, irritability, and mild nerve damage. The Institute of Medicine of the National Academy of Sciences has set a tolerable upper intake level (UL) for selenium at 400 micrograms per day for adults to prevent the risk of developing selenosis.

Selenium toxicity is rare in the United States. The few reported cases have been associated with industrial accidents and a manufacturing error that led to an excessively high dose of selenium in a supplement. Brazil nuts contain very high amounts of selenium (68 to 91 mcg per nut), so limit yourself to one nut per day.

how do you get rid of selenosis?

The carbon diselenide (not carbonate) is CSe2.

Selenium typically has an ionic charge of -2 when forming compounds.

Selenocysteine is the amino acid that contains selenium. It is incorporated into proteins during the translation process via a specific codon and tRNA. Selenium plays a role in antioxidant defense and thyroid hormone metabolism.

In its standard state, selenium exists as a grey, metallically lustrous solid with a crystalline structure. It is a nonmetal with properties that are intermediate between sulfur and tellurium. Selenium is typically found in nature in its elemental form or in various minerals.

Selenium is a trace mineral essential for many bodily functions. It does not have blood-thinning properties like medications such as aspirin or warfarin. Consuming the recommended daily amount of selenium from food sources is beneficial for overall health, but it does not specifically affect blood clotting.

An element loses 4s electrons before 3d electrons because the 4s orbital has a higher energy level (n value) than the 3d orbital. When an atom loses electrons to form a cation, it tends to lose the electrons from the outermost shell first, which in this case is the 4s orbital.

Selenium a non metal hexagonal grey element has 34 protons and electrons. The atomic structure of Selenium has 45 neutrons.

First, we need to convert micrograms to grams by dividing by 1,000,000. Then, we can use the molar mass of selenium (78.971 g/mol) to find the number of moles. So, 56 micrograms of selenium is equal to 0.000056 grams, which corresponds to approximately 7.07 x 10^-7 moles of selenium.

The chemical formula of iron(III) and selenium is Fe2Se3 - iron(III) selenide.

The atomic number of Selenium is 34.

Selenium is only a chemical element !

Selenium is named after the Greek word "Selene," which means moon, due to its similarity to tellurium, which is named after the Earth. This naming convention follows the tradition of associating elements with celestial bodies based on their chemical properties.

Selenium has four half-filled orbitals - the 4s, 4p_x, 4p_y, and 4p_z orbitals. This is because selenium has four electrons in its 4th energy level.

Selenium is a trace element that plays a role in antioxidant defense, thyroid hormone metabolism, and immune function. While it may have indirect benefits for joint health by reducing inflammation and oxidative stress, it does not directly build cartilage. Consuming adequate selenium through diet or supplements is important for overall health, including joint health.

selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.

In the Greek mythology Selene is the Moon goddess.

There are 34 protons in a selenium-76 atom.
