The ion is S22-
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2
There are two atoms of sulfur in pyrite (FeS2)
Actually it is about the orbitals of valence shells of sulphur. Sulphur has atomic no. 16 and electronic configuration 1s2,2s2,2p6,3s2,3p4. Its outer most shell has s.p.d and f orbitals from which s and p have electrons and d and f are vacant. When 2 electrons from p are transferred to d, the valency becomes +2. When two more electrons from p are transfered to d, the valency becomes +4. When two left electrons from s are transferred to d, the valency becomes +6.
6. The oxidation number of sulfur is +6. Another approach if you are not familiar with oxidation number is to draw Lewis dot diagrams for sulfate ion, these will have 2 double bonds and two single bonds (single bonds attaching negative charged oxygen atoms) and will show will show 6 bonds from sulfur.
The valency of sulfur in ammonium sulfate is 6. This is because each sulfate ion (SO4^2-) contains one sulfur atom with a valency of 6 due to its ability to form 6 covalent bonds by accepting two electrons from each of the four oxygen atoms.
The S valence would be -1 when Fe(II) is 2+. In most cases sulfur has one negative and two possible positive valences: -2 and +4 or +6. So FeS2 is not a possible, or maybe a very rare, compound (Iron(II) persulfide?).
The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2

Carbon has a valency of 4, while sulfur has a valency of 6.
The valency of sulfur in sulfuric acid is 6. Sulfuric acid has the chemical formula H2SO4, indicating that sulfur forms 6 bonds, with each oxygen atom contributing 2 bonds.
An iron sulfide is obtained: FeS2.
iron and sulfur Pyrite is iron sulfide, FeS2.
The valency of sulfur in the sulfite radical is +4. This is because sulfur has a usual oxidation state of +4 in the sulfite ion, which is SO3^2-.
Fes2, also known as iron disulfide or pyrite, contains three atoms - one iron (Fe) atom and two sulfur (S) atoms.
The valency of sulfur in sulfuric acid (H2SO4) is +6. This means that sulfur can form up to 6 chemical bonds with other elements.
The valency of sulfur in hydrogen sulfide is 2. This means that sulfur in hydrogen sulfide forms two bonds with other elements or ions, such as hydrogen in this case.
