Oxygen is divalent, but sulphur exhibits variable valency of 2, 4 and 6 because of the presence of d -orbitals in sulphur. In sulphur, the excitation of np -electrons to nd -sub-shell gives rise to increase in number of unpaired electrons. Option D is correct.
Sulfur has variable valency because it can form different numbers of bonds with other elements. Sulfur can exhibit valencies of +2, +4, or +6 depending on the specific compound and bonding arrangements. This flexibility is due to sulfur's ability to expand its valence electron shell by using its d orbitals in addition to its s and p orbitals.

Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What non-metals has no variable valency Zn Cu Fe N?
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
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.
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-.
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 sulfur?
The valency of sulfur is typically 2, 4, or 6, depending on the compound it forms.
What is the valency of sulfur in FeS2?
The valency of sulfur in FeS2 is -2. This is because the overall charge of FeS2 is zero, and iron has a positive valency of +2. Therefore, sulfur must have a valency of -2 to balance the charge.
Which element has 4 and 6 valency?
Carbon has a valency of 4, while sulfur has a valency of 6.
What non-metals has no variable valency Zn Cu Fe N?
Out of the non-metals you listed, nitrogen (N) is the only one that does not exhibit variable valency. Zinc (Zn), copper (Cu), and iron (Fe) can exhibit variable valency in certain compounds.
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.
What is the valency of sulphur in ammonium sulphate?
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.
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-.
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 do you mean by variable valency?
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)
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.
What is valency of sulphur in sulphuric acid?
The valency of sulfur in sulfuric acid (H2SO4) is +6. Sulfur forms 4 covalent bonds (with oxygen atoms) and 2 ionic bonds (with hydrogen ions) in the compound.
