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.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
The chemical formula for magnesium sulfate is: MgSO4
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.
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.
Neither H2O nor MgSO4 are elements. They are COMPOUNDS. In terms of volume occupied , MgSO4 is the larger.
You don't say that. What you do say is that the valency of sulphur in sulphur trioxide is 6.
Things are complicated if we use the term valency. It is better to use the term Oxidation state or Oxidation Number. In SO2, the oxidation state of sulphur is +4 and In SO3, the oxidation state of sulphur is +6.
Carbon has a valency of 4, while sulfur has a valency of 6.
The valency of magnesium in MgSO4 is +2. Magnesium typically forms ionic compounds with a +2 charge due to its tendency to lose two electrons to achieve a stable electron configuration.
The chemical formula for magnesium sulfate is: MgSO4
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-.
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.
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 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.

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.
