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.

Why is valency of sulphate -2?
Because sulfur is +6 (6 valence electrons) but there are 4 oxygens at -2 bound to it so its net charge is +6 - 4 x -2 = -2
What is the valency of sulphur in so2?
38.
What is the valency of sulphur in SO3?
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.
What is the valency of trioxide?
S = +6 valency O = -2 valency
What is the oxidation of sulfur?
Sulfur can have a wide range of oxidation in its compounds -2 in H2S 0 in elementary sulfur (S8) +4 in SO2 +6 in SO3
Why is valency of sulphate -2?
Because sulfur is +6 (6 valence electrons) but there are 4 oxygens at -2 bound to it so its net charge is +6 - 4 x -2 = -2
What is the valency of sulfur in sulfuric acid?
+6 valency
What is the valency of ferrum?
2, 3, 4, 6.
What is the valency of sulphur in so2?
38.
Why does sulfur have variable valency?
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.
What is the valency of sulphur in SO3?
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.
What is the valency of trioxide?
S = +6 valency O = -2 valency
What is the valency of platinum?
Possible valences are (+1), +2, (+3), +4, +6
Which element has 4 and 6 valency?
Sulphur
What is the valency of Rutherfordium Dubnium Seaborgium Bohrium Hassium Meitnerium?
valency of Rf =4 valency of Db=5 valency of Sg=6 valency of Bh=7 valency of Hs=8 valency of Mt=unknown
What is the oxidation number for each sulfur atoms?
It is different compound to compound. Sulfur generally shows +6 and +4.
How many valence electrons does Sulfur?
there are 6 electrons in valence shell of sulphur so it accepts two electrons to complete the octet (8 electrons in last shell) so its valency in ionic compounds is always - 2.
