    The ground state of S 2 is a triplet: a diradical, with two unpaired electrons like O 2 and SO. [6] It has the S-S bond length of 189 pm, much shorter than the S-S single bonds in S 8, which are 206 pm long. Its Raman spectrum consists of a band at 715 cm −1. [7] The corresponding O-O band for O 2 is found at 1556 cm −1. [8] The S-S bond ...

  5. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    Because the S 2− anion has a subscript of 2 in the formula (giving a 4− charge), the compound must be balanced with a 4+ charge on the Pb cation (lead can form cations with a 4+ or a 2+ charge). Thus, the compound is made of one Pb 4+ cation to every two S 2− anions, the compound is balanced, and its name is written as lead(IV) sulfide.

    Sulfur polycations, S 8 2+, S 4 2+ and S 16 2+ are produced when sulfur is reacted with oxidising agents in a strongly acidic solution. [1] The colored solutions produced by dissolving sulfur in oleum were first reported as early as 1804 by C.F. Bucholz, but the cause of the color and the structure of the polycations involved was only ...

    en.wikipedia.org/wiki/Sulfur_oxide

    Sulfur oxide refers to many types of sulfur and oxygen containing compounds such as SO, SO 2, SO 3, S 7 O 2, S 6 O 2, S 2 O 2, etc. Sulfur oxide (SO x) refers to one or more of the following: Lower sulfur oxides (S n O, S 7 O 2 and S 6 O 2) Sulfur monoxide (SO) and its dimer, Disulfur dioxide (S 2 O 2) Sulfur dioxide (SO 2) Sulfur trioxide (SO 3)

  8. Lead(II) sulfide - Wikipedia

    en.wikipedia.org/wiki/Lead(II)_sulfide

    Addition of hydrogen sulfide or sulfide salts to a solution containing a lead salt, such as PbCl 2, gives a black precipitate of lead sulfide. Pb 2+ + H 2 S → PbS↓ + 2 H + This reaction is used in qualitative inorganic analysis. The presence of hydrogen sulfide or sulfide ions may be tested using "lead acetate paper."

  9. Disulfide - Wikipedia

    en.wikipedia.org/wiki/Disulfide

    In chemistry, a disulfide (or disulphide in British English) is a compound containing a R−SS−R′ functional group or the S 22 anion.The linkage is also called an SS-bond or sometimes a disulfide bridge and usually derived from two thiol groups.
