Selenium

Yes, selenium can combine with elements such as oxygen, hydrogen, sulfur, and metals to form a variety of compounds. It can form selenides with metals and oxides with non-metals. These compounds have a wide range of applications in medicine, industry, and research.

Freezing /Melting Point: 217.0 °C (422.6 °F)

The noble gas electron configuration of selenium is [Ar] 3d^10 4s^2 4p^4 and for phosphorus is [Ne] 3s^2 3p^3. These configurations indicate how the electrons are arranged in the outermost energy levels of the atoms, resembling the stable electron configurations of noble gases.

Selenium is a nonmetal because it lacks the physical and chemical properties of metals. It tends to gain electrons in reactions rather than losing them like metals, and it is brittle in solid form rather than malleable and ductile like metals. Additionally, selenium is a poor conductor of heat and electricity, unlike metals.

Selenium and mercury can form an attraction due to their opposite charges and the formation of intermolecular forces, such as Van der Waals interactions and dipole-dipole forces. These interactions can create bonds between the two elements, leading to an attractive force between selenium and mercury.

Selenium is a nonmetal with properties that vary depending on the form it takes. In its crystalline form, selenium is a semiconductor with photoconductive properties. It is also known to exhibit photovoltaic and photoresistive behavior. Additionally, selenium is unique in its ability to exist in various oxidation states (-2, +2, +4, +6).

The chemical equation for the reaction between barium and selenium is: Ba + Se → BaSe. This reaction forms barium selenide.

There is one mole of selenium in one mole of selenium tetrafluoride, as the formula for selenium tetrafluoride is SeF4. Therefore, there is 1 mole of selenium in 1 mole of selenium tetrafluoride.

The compound formed between lithium and selenium would have the chemical formula Li2Se. This is because lithium is in Group 1 of the periodic table and has a +1 charge, while selenium is in Group 16 and has a -2 charge.

Locoweed is a plant that can accumulate high levels of selenium from the soil. When livestock like cattle graze on locoweed, they can ingest toxic amounts of selenium, which can lead to selenium poisoning and various health issues.

No, selenium is a chemical element found on the periodic table with the atomic number 34 and symbol Se. It is a non-metal element that can exist in various forms, such as pure elemental selenium or in compounds with other elements.

Selenium was named after the Greek word "selene," which means moon. This is because selenium's properties were found to be similar to tellurium, which was named after the Earth, and sulfur, which was named after the Sun. The name selenium reflects its position in the same chemical group as tellurium and sulfur.

The average adult human body contains about 95 grams of chlorine, mainly found in the form of chloride ions in bodily fluids such as blood and digestive juices. Chlorine is an essential electrolyte that helps maintain fluid balance, transmit nerve impulses, and regulate pH levels in the body.

No, selenium dioxide (SeO2) has a bent or V-shaped molecular geometry due to its lone pairs on the selenium atom. It is best described as having a bent molecular shape rather than a trigonal planar geometry.

Selenium gains two electrons to achieve a stable electron configuration, usually by forming ionic compounds in which it takes on a -2 charge.

Selenium is an essential mineral that plays a role in various bodily functions, but it is not directly linked to bone health. Calcium, vitamin D, and other minerals like magnesium and phosphorus are more crucial for maintaining healthy bones. However, selenium does support overall health and may indirectly contribute to bone health by its antioxidant properties.

Selenium typically loses 2 electrons to achieve a stable electron configuration. This results in the formation of a 2+ ion for selenium.

Selenium and vitamin E are both powerful antioxidants that work together synergistically to protect cells from damage caused by free radicals. Vitamin E helps to neutralize free radicals in the cell membranes, while selenium works to regenerate vitamin E, allowing it to continue its antioxidant function. Together, they can enhance each other's antioxidant properties and provide greater protection against oxidative stress.

Yes, Selenium's long term usage can cause type 2 diabetes as it affects the blood sugar level and may cause obesity. It is an anti-oxidant and its good for health if used in proper amount and not as a regular consumption.

Too much of anything is not good :))

In some cases, supplementation of selenomethionine (a type of selenium) may result in better conversion of T4 to T3, sometimes resulting in lowered cholesterol levels and raised thyroid levels within the body. In some cases selenomethionine supplementation can result in the remission of Hashimoto's thyroiditis.

Arsenic poisoning can lead to symptoms such as abdominal pain, diarrhea, skin discoloration, and in severe cases, it can cause organ damage and increase the risk of certain cancers. Selenium poisoning can cause symptoms like nausea, weakness, hair loss, and skin lesions, and in severe cases, it can lead to respiratory distress and neurological issues.

Potassium and selenium can form an ionic bond, where potassium will donate an electron to selenium to achieve a stable electron configuration. This results in the formation of potassium selenide (K2Se).

Ultimately, the number of electrons would not change, however, the position of elements of the periodic table according to their respective quantizied energy levels would change. For instance, on the periodic table one sharp would have hydrogen helium and lithum, proceeded by two sharp with beryllium, boron and carbon. Two principle would contain nitrogen, oxygen and flouride.

This would merely be an assumption.

Selenium is an element it was "made" in the nova of an exploding star several billion years ago.
Selenium is found on Earth in minerals such as pyrites where it partially replaces the sulfides. Native selenium is very rare. Most elemental selenium on the market comes as a byproduct of metal refining such as copper or the production of sulfuric acid.
