  2. Chalcogen - Wikipedia

    en.wikipedia.org/wiki/Chalcogen

    Chalcogens also form compounds with halogens known as chalcohalides, or chalcogen halides. The majority of simple chalcogen halides are well-known and widely used as chemical reagents . However, more complicated chalcogen halides, such as sulfenyl, sulfonyl, and sulfuryl halides, are less well known to science.

  3. List of alternative nonmetal classes - Wikipedia

    en.wikipedia.org/wiki/List_of_alternative...

    This results in six or seven sets of nonmetals, depending on the treatment of boron, which in some cases is regarded as a metalloid. The size of the group 14 set, and the sets of nonmetal pnictogens, chalcogens, and halogens will vary depending on how silicon, germanium, arsenic, antimony, selenium, tellurium, and astatine are treated.

  4. Chalcogen bond - Wikipedia

    en.wikipedia.org/wiki/Chalcogen_bond

    In chemistry, a chalcogen bond (ChB) is an attractive interaction in the family of σ-hole interactions, along with halogen bonds. [ 1 ] [ 2 ] Electrostatic , charge-transfer (CT) and dispersion terms have been identified as contributing to this type of interaction.

    The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...

  7. Hydrogen chalcogenide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chalcogenide

    Hydrogen shares many properties with the halogens; substituting the hydrogen with halogens can result in chalcogen halide compounds such as oxygen difluoride and dichlorine monoxide, alongside ones that may be impossible with hydrogen such as chlorine dioxide.

  8. Halogen bond - Wikipedia

    en.wikipedia.org/wiki/Halogen_bond

    In chemistry, a halogen bond ... The σ-hole concept readily extends to pnictogen, chalcogen and aerogen bonds, corresponding to atoms of Groups 15, ...

  9. Interchalcogen - Wikipedia

    en.wikipedia.org/wiki/Interchalcogen

    The chalcogens react with each other to form interchalcogen compounds. [1]Although no chalcogen is extremely electropositive, [note 1] nor quite as electronegative as the halogen fluorine (the most electronegative element), there is a large difference in electronegativity between the top (oxygen = 3.44 — the second most electronegative element after fluorine) and bottom (polonium = 2.0) of ...
