The answer is SeF6.
This is figured by:
2.231 grams of Se divided by 78.79 g/mol = 0.0283 moles of Se
3.221 grams of F divided by 18.998 g/mol = 0.1695 moles of F
0.1695 moles of Se/0.0283 moles of F = 5.9909 ~ 6 moles of Se/mole of F
So SeF6
What is an important function of selenium?
Selenium is an essential mineral that serves as a powerful antioxidant in the body, helping to protect cells from damage caused by free radicals. It also plays a crucial role in thyroid function and supports a healthy immune system.
Selenium is mainly absorbed in the small intestine, specifically in the jejunum and ileum. It is absorbed through the process of passive diffusion and is then transported to the liver for distribution throughout the body.
Who is the Vendor for selenium automation tool?
Selenium is an open-source automation tool suite primarily maintained by the Selenium community through contributions from individuals and organizations worldwide. The project does not have a single official vendor or company behind it.
Does selenium act as an antioxidant?
Yes, selenium is an essential mineral that functions as an antioxidant in the body. It helps protect cells from damage caused by free radicals and supports the immune system. Consuming adequate amounts of selenium through diet or supplements is important for overall health.
Can you take sea kelp and selenium while taking thyroid replacement?
It is important to consult with your healthcare provider before taking sea kelp or selenium supplements while on thyroid replacement therapy. Sea kelp can contain high levels of iodine, which could potentially interfere with thyroid hormone levels, and selenium may have potential interactions with thyroid medications. Your healthcare provider can advise on the proper dosages and any potential risks or benefits of combining these supplements with thyroid replacement therapy.
Is selenium water or fat-soluble?
Selenium is not soluble in water. Like sulfur, though, it does dissolve in a rather nasty liquid called carbon disulfide, and in toluene, also called methyl benzene, and some of its relatives. All these liquids require handling in a fume cupboard and with precautions to stop their catching fire.
Selenium in treatment of tinea corpora?
Selenium sulfide is commonly used in the treatment of tinea corporis (fungal infection of the body). It works by reducing the growth of the fungus and helping to alleviate symptoms such as itching and scaling. It is available in a topical formulation for application to the affected skin.
What is the balanced equation of lithium and selenium?
The balanced equation for the reaction between lithium and selenium is 2Li + Se -> Li2Se.
Formula for ionic elements aluminum and selenium?
The ionic formula for aluminum is Al3+ and for selenium is Se2-. When these two ions combine, the formula for the resulting ionic compound is Al2Se3.
Slogans for periodic table element selenium?
Is selenium sulfide good for hair lose?
Selenium sulfide is primarily used to treat dandruff and seborrheic dermatitis. It is not typically recommended for hair loss. If you are experiencing hair loss, it is best to consult with a healthcare professional to determine the underlying cause and appropriate treatment.
What compounds does the selenium atom have the most positive partial charge?
In CuO the oxidation state of Cu is +2 and is called cupric oxide, or copper-II oxide (do NOT pronounce as dioxide).
In Cu2O the oxidation state of Cu is +1 and is called cuprous oxide, or copper I oxide or di-copper oxide.
What is the treatment for selenium deficiency?
Selenium deficiency is typically treated with selenium supplements or by increasing intake of selenium-rich foods such as Brazil nuts, seafood, and meats. It's important to consult with a healthcare provider to determine the appropriate dosage and duration of supplementation.
What are the chemical and physical properties of selenium?
Selenium is a nonmetal element with the atomic number 34. It is a brittle solid at room temperature with a metallic luster. It exhibits both photovoltaic and photoconductive properties, making it useful in solar cells and photocopying.
Selenium is a semiconductor that can conduct electricity under certain conditions. Its chemical properties include forming compounds with both metallic and nonmetallic elements, and it is essential for various biological functions in trace amounts.
Selenium commonly bonds with hydrogen, oxygen, and sulfur in various chemical compounds. It forms covalent bonds with these elements to create selenides (with metals), selenates (with oxygen), and selenites (with sulfur), among others. Selenium also forms bonds with other nonmetals, such as carbon and nitrogen, in organic compounds.
DL Phenylalanine is not a vitamin, it is an amino acid. Amino acids are the building blocks of protein. This amino acid, when taken as a supplement, can reduce pain, increase alertness, improve mood and may help Parkinson's disease.

What is the product of selenium dioxide plus aqueous potassium hydroxide?
The reaction between selenium dioxide and aqueous potassium hydroxide forms selenites, or salts containing the SeO3^2- ion, and water. This reaction can be represented as SeO2 + 2KOH + H2O → K2SeO3 + H2O.
What elements does selenium combine with?
Selenium can combine with a variety of elements, including oxygen, sulfur, hydrogen, and metals such as mercury, copper, and silver. It forms a range of compounds with different properties and applications in industry, biology, and chemistry.
How did mendeleev place arsenic and selenium?
Mendeleev placed arsenic before selenium in his periodic table based on their atomic weights and chemical properties. Arsenic has a lower atomic weight and exhibits similar chemical behavior to other elements in its group, making it a better match for the position before selenium.
What is selenium's mass number?
Selenium's mass number is 79. It is the sum of the number of protons and neutrons in the nucleus of a selenium atom.
In what group is selenium in the periodic table?
Selenium (Se) is in oxygen family (group 16 or VIA) and in 4th period.
Phosphorus sulfur and selenium which has the largest atom?
Selenium has the largest atom among phosphorus, sulfur, and selenium because of its larger atomic radius. This is due to selenium having more electron shells and thus a greater distance from the nucleus.
