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.
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)

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 ...
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)
