What are massive deposits of limestone?
Massive deposits of limestone are large accumulations of sedimentary rock composed primarily of calcium carbonate. These deposits can form when calcium-rich marine organisms such as corals and shellfish accumulate and solidify over time. Limestone has many commercial uses, including in construction and as a raw material for cement production.
What is the nature of the Se-Cl bond in a molecule of selenium chloride SeCl2 if the electronegativity value of selenium is 2.55 and that of chlorine is 3.16?
The Se-Cl bond in selenium chloride SeCl2 is polar covalent. This is because chlorine has a higher electronegativity than selenium, resulting in an uneven sharing of electrons in the bond. Chlorine, being more electronegative, attracts the shared electrons more towards itself, giving it a partial negative charge and selenium a partial positive charge.
What is more reactive calcium or more reactive?
Calcium is more reactive but not as Potassium or Sodium because according to the displacement series Calcium comes as third and the last under the reactive elements of the displacement series.
What is the name for the compound SeF2?
The compound SeF2 is known as selenium difluoride.
How many neutrons are in selenium-76?
Selenium-76 has 46 neutrons. This can be calculated by subtracting the atomic number (34) from the mass number (76) of selenium.
Why does calcium and selenium bond together?
Calcium and selenium can form bonds together due to their differing electronegativities, which allows for an attraction between the positively charged calcium ion and the negatively charged selenium ion. This bond formation helps stabilize both elements by achieving a more favorable electron configuration.
What is selenium combined with calcium?
Selenium combined with calcium is a mineral supplement that provides both selenium and calcium in a single dosage. Selenium is an essential mineral with antioxidant properties, while calcium is vital for bone health and muscle function. This combination may help support overall health, especially for individuals who have deficiencies in either mineral.
What type bond will it be if calcium and selenium bond?
Calcium and selenium would likely form an ionic bond, with calcium losing 2 electrons to become a positively charged ion and selenium gaining 2 electrons to become a negatively charged ion.
What is the formula of the ion compound formed by calcium and selenium?
Calcium selenide, CaSe, is formed.
How do selenium and calcium bond?
Selenium and calcium do not typically bond together. Selenium tends to form bonds with oxygen or sulfur atoms, while calcium commonly forms bonds with oxygen atoms. Each element tends to form stable compounds with specific types of atoms rather than with each other.
Are inorganic nutrients bad for you?
No. There are many inorganic nutrients that we abolutely need. Magnesium, Calcium, Selenium, Chromium, all come to mind. There are many more....
Is selenite a element?
Selenite is not an element. It is a mineral composed of calcium sulfate, which is a compound made up of calcium, sulfur, and oxygen atoms. The chemical formula for selenite is CaSO4·2H2O.
Is selenium or sulfur more reactive?
sulfur is more reactive than selenium
What type of minerals are found in cheese?
From highest to lowest in milligrams: calcium, sodium, phosphorus, potassium, magnesium, selenium, fluoride and iron.
Which is more metallic oxygen vs selenium?
Selenium is more metallic than oxygen. Oxygen is a non-metal, while selenium is a metalloid that exhibits some properties of metals.
Is selenium good for bones?
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.
What is the formula for calcuim and selenium?
Sulfur and phosphorus would most like form the compound P2S5
