Valency of sulphur: 65 answers 61

Valency of sulphur in SO3 = + 6 Hope it helps ️ Explore all similar answers arrow right heart outlined The sulphur atom has 6 electrons in the outermost shell, and its valency could be 6. But it is easier for sulphur to gain two electrons instead of losing six electrons. Hence, its valency is determined by subtracting six electrons from the octet and this gives a valency of two for sulphur. Calculation of valency: Valency of Sulphur: The electronic configuration of Sulphur=2, 8, 6. Since, Sulphur has 6 (more than 4) electrons in its outermost shell. Therefore, valency of sulphur = 8 - number of electrons in outermost shell = 8 6 = 2 Hence, from above we can conclude that option A is the correct option for the given question. In Sulphur dioxide, Sulphur is bonded to 2 oxygen atoms. Oxygen is more electronegative than Sulphur and thus, shows a fixed valency of 2. As a result each oxygen forms two bonds with the Sulphur atom making its valency 4. In Sulphur trioxide, Sulphur is bonded to 3 oxygen atoms.
