  2. Chalcogen - Wikipedia

    en.wikipedia.org/wiki/Chalcogen

    Even though oxygen is a chalcogen, its chemical properties are different from those of other chalcogens. One reason for this is that the heavier chalcogens have vacant d-orbitals . Oxygen's electronegativity is also much higher than those of the other chalcogens.

  3. Hydrogen chalcogenide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chalcogenide

    Its properties are somewhat distinct from the rest of the hydrogen chalcogenides, since polonium is a metal while the other chalcogens are not, and hence this compound is intermediate between a normal hydrogen chalcogenide or hydrogen halide such as hydrogen chloride, and a metal hydride like stannane. Like water, the first of the group ...

  4. Chalcogen bond - Wikipedia

    en.wikipedia.org/wiki/Chalcogen_bond

    A means of comparing the chalcogen-chalcogen bonding forces with H-bonding is to compare the effect of various solvent environments on the chalcogen-chalcogen bond. This has been done on a series of molecules featuring a chalcogen-chalcogen intramolecular bond in one conformation (closed) and exposed to solvent interactions in another (open).

  5. Chalcogenide - Wikipedia

    en.wikipedia.org/wiki/Chalcogenide

    A chalcogenide is a chemical compound consisting of at least one chalcogen anion and at least one more electropositive element. Although all group 16 elements of the periodic table are defined as chalcogens, the term chalcogenide is more commonly reserved for sulfides, selenides, tellurides, and polonides, rather than oxides.

  6. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    Physical properties; ... It is a member of the chalcogen group in the periodic table, ... Epoxides are ethers in which the oxygen atom is part of a ring of three atoms.

  7. List of elements by atomic properties - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by_atomic...

    This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.

  8. Chalcogenidotetrelate - Wikipedia

    en.wikipedia.org/wiki/Chalcogenidotetrelate

    The tetrel atom has one, two, three or four single bonds to chalcogen atoms, or one double bond plus one or two single bonds to chalcogen atoms. The tetrel atom would normally have four bonds in a +4 oxidation state. Carbon differs significantly from the other elements in seldom having four single bonds to chalcogens, and so has few compounds ...

  9. Indium chalcogenides - Wikipedia

    en.wikipedia.org/wiki/Indium_chalcogenides

    The indium chalcogenides include all compounds of indium with the chalcogen elements, oxygen, sulfur, selenium and tellurium. (Polonium is excluded as little is known about its compounds with indium). The best-characterised compounds are the In(III) and In(II) chalcogenides e.g. the sulfides In 2 S 3 and InS.
