  3. Group 9 element - Wikipedia

    en.wikipedia.org/wiki/Group_9_element

    Group 9, by modern IUPAC numbering, [1] is a group (column) ... This is to clean it of its sulfur content, which is very polluting when burned and causes acid rain.

  4. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.

  5. Main-group element - Wikipedia

    en.wikipedia.org/wiki/Main-group_element

    The main group includes the elements (except hydrogen, which is sometimes not included [citation needed]) in groups 1 and 2 , and groups 13 to 18 . The s-block elements are primarily characterised by one main oxidation state, and the p-block elements, when they have multiple oxidation states, often have common oxidation states separated by two ...

  6. Chalcogen - Wikipedia

    en.wikipedia.org/wiki/Chalcogen

    Dmitri Mendeleev's periodic system proposed in 1871 showing oxygen, sulfur, selenium and tellurium part of his group VI. Three of the chalcogens (sulfur, selenium, and tellurium) were part of the discovery of periodicity, as they are among a series of triads of elements in the same group that were noted by Johann Wolfgang Döbereiner as having ...

  7. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    Compounds that contain sulfur exhibit unique chemistry due to sulfur's ability to form more bonds than oxygen, its lighter analogue on the periodic table. Substitutive nomenclature (marked as prefix in table) is preferred over functional class nomenclature (marked as suffix in table) for sulfides, disulfides, sulfoxides and sulfones.

  8. Organic sulfide - Wikipedia

    en.wikipedia.org/wiki/Organic_sulfide

    General structure of a sulfide with the blue marked functional group. In organic chemistry, a sulfide (British English sulphide) or thioether is an organosulfur functional group with the connectivity R−S−R' as shown on right. Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1]

  9. Organosulfur chemistry - Wikipedia

    en.wikipedia.org/wiki/Organosulfur_chemistry

    Sulfur shares the chalcogen group with oxygen, selenium, and tellurium, and it is expected that organosulfur compounds have similarities with carbon–oxygen, carbon–selenium, and carbon–tellurium compounds. A classical chemical test for the detection of sulfur compounds is the Carius halogen method.
