A selenide is a chemical compound containing a selenium anion with oxidation number of −2 (Se 2 − ), much as sulfur does in a sulfide. The chemistry of the selenides and sulfides is similar. Similar to sulfide, in aqueous solution, the selenide ion, Se 2 − , is prevalent only in very basic conditions.

What is a selenium deficiency?
Selenium deficiency occurs when there is inadequate dietary intake of selenium , typically due to a scarcity of selenium sources in a given region. Interestingly, many selenium-deficiency diseases are linked with concurrent vitamin E deficiency.
Is selenium safe to take daily?
When taken by mouth: Selenium is LIKELY SAFE for most people when taken by mouth in doses less than 400 mcg daily, short-term. However, selenium is POSSIBLY UNSAFE when taken by mouth in high doses or for a long time. Taking doses above 400 mcg can increase the risk of developing selenium toxicity.
What is the ion charge for SE?
Elemental Se has a charge of 0 .
What is the symbol of tellurium?
Tellurium is a chemical element with the symbol Te and atomic number 52. It is a brittle, mildly toxic, rare, silver-white metalloid. Tellurium is chemically related to selenium and sulfur, all three of which are chalcogens.
What is the name of al3+?

- fatigue.
- mental fog.
- hair loss.
- weakened immune system.
What happens if you don’t get enough selenium?
Selenium deficiency can cause Keshan disease (a type of heart disease) and male infertility. It might also cause Kashin-Beck disease, a type of arthritis that produces pain, swelling, and loss of motion in your joints.
What is the best form of selenium to take?
What is the best form of selenium supplements? Selenium is available as selenomethionine, selenocysteine, selenite, and selenate (1). Selenomethionine and selenocysteine are better absorbed by the gut (11).
Can selenium make you gain weight?
Too little selenium in the diet and the thyroid cannot function properly, resulting in a compromise in metabolic rate. A slower metabolic rate will usually lead to weight gain. Get too much selenium in the diet and you run the risk of toxicity.
What is the benefit of selenium?
Selenium plays an important role in the health of your immune system . This antioxidant helps lower oxidative stress in your body, which reduces inflammation and enhances immunity. Studies have demonstrated that increased blood levels of selenium are associated with enhanced immune response.
Does selenium raise blood pressure?
However, various studies have shown that increasing Se levels above the recommended daily intake is not beneficial and can actually cause hypertension, diabetes and hyperlipidaemia ( 8 ) .
What is the charge of H?
The hydrogen ion has a positive charge of 1 (i.e.) +1 . We know that hydrogen has one proton and one electron. If it loses one electron to form an ion, the charge of the hydrogen ion becomes +1.
Is co3 positive or negative?
The substance with the chemical formula CO 3 goes by the name carbonate. Carbonate is made of 1 atom of carbon and 3 atoms of oxygen and has an electric charge of −2. This negative charge means that a single ion of carbonate has 2 more electrons than protons.
