What is the valency of sulphur in FeS2?

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?).


What is the Valency of sulfur?

The valency of sulfur is 2-. The valency of sulfur is 2-. The valency of sulfur (S) is +2


How many atoms of sulfur are in pyrite?

There are two atoms of sulfur in pyrite (FeS2)


Which element has 4 and 6 valency?

Carbon has a valency of 4, while sulfur has a valency of 6.


What is the valency of sulfur in sulfuric acid?

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.


Was there was a substance formed after heating the iron-sulfur mixture?

An iron sulfide is obtained: FeS2.


What elements make iron pyrite?

iron and sulfur Pyrite is iron sulfide, FeS2.


What is the valency of sulphur in sulphite radical?

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-.


How many atoms does Fes2 have?

Fes2, also known as iron disulfide or pyrite, contains three atoms - one iron (Fe) atom and two sulfur (S) atoms.


What is the valency of sulphur in sulphuric acid?

The valency of sulfur in sulfuric acid (H2SO4) is +6. This means that sulfur can form up to 6 chemical bonds with other elements.


What is the valency of sulphur in hydrogen sulphide?

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.


Why valency of sulfur is 2 4 and 6?

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.
