Selenium forms two oxides: selenium dioxide (SeO 2) and selenium trioxide (SeO 3). Selenium dioxide is formed by the reaction of elemental selenium with oxygen: [5] + It is a polymeric solid that forms monomeric SeO 2 molecules in the gas phase. It dissolves in water to form selenous acid, H 2 SeO 3.
A hexachloride is a compound or ion that contains six chlorine atoms or ions. It is the highest chloride that an element can form. Common hexachlorides include: Molybdenum hexachloride, MoCl 6; Tungsten hexachloride, WCl 6; Rhenium hexachloride, ReCl 6; Uranium hexachloride, UCl 6; Some hexachloroanions are also known: Hexachloroaluminate [AlCl ...

Selenium oxydichloride is the inorganic compound with the formula SeOCl 2. It is a colorless liquid. With a high dielectric constant (55) and high specific conductance, it is an attractive solvent. Structurally, it is a close chemical relative of thionyl chloride SOCl 2, being a pyramidal molecule.
For example, in phosphorus pentafluoride (PF 5), 5 resonance structures can be generated each with four covalent bonds and one ionic bond with greater weight in the structures placing ionic character in the axial bonds, thus satisfying the octet rule and explaining both the observed trigonal bipyramidal molecular geometry and the fact that the ...
Selenium tetrachloride is the inorganic compound composed with the formula SeCl 4. This compound exists as yellow to white volatile solid. This compound exists as yellow to white volatile solid. It is one of two commonly available selenium chlorides , the other example being selenium monochloride , Se 2 Cl 2 .
Selenite refers to the anion with the chemical formula Se O 2− 3. It is the oxyanion of selenium. It is the selenium analog of the sulfite ion, SO 2− 3. Thus selenite is pyramidal and selenium is assigned oxidation state +4. Selenite also refers to compounds that contains this ion, for example sodium selenite Na 2 SeO 3 which is a common ...
Selenium dioxide is the chemical compound with the formula SeO 2. This colorless solid is one of the most frequently encountered compounds of selenium . It is used in making specialized glasses as well as a reagent in organic chemistry.
