It is CaSe
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.
Gypsum and selenite are chemically similar as they both are forms of calcium sulfate with the same chemical formula (CaSO4·2H2O). They have the same crystal structure but differ in their crystal habits - gypsum typically forms as massive white rocks, whereas selenite forms clear and prismatic crystals.
The molecular formula for silver selenite is Ag2SeO3.Silver selenite is an inorganic compound which forms crystalline needles.
Lithium is Li^+ , and selenite is SeO3^2-. It will take 2 Li^+ for each SeO3^2-, so the formula is Li2SeO3
Fe2(SeO3)3
Al(HSeO3)3
Selenite is formed through the evaporation of water with high concentrations of calcium and sulfate ions. Over time, these ions combine and crystallize to form selenite structures, typically in underground caves or as mineral deposits in sedimentary environments. Temperature, pressure, and the presence of other minerals can also influence the formation of selenite.
The chemical formula for Calcium Silicate is Ca2SiO4.
Calcium doesn't have a formula. It is an element.
The formula for calcium chromate is CaCrO4.
The chemical formula for Calcium Chloride is CaCl2.
The chemical formula for calcium sulphite is CaSO3
