So in order to achieve stability, sulfur has to gain 2 electrons. Because that the electrons try to stay as far away from each other as possible according to Valence Shell Electron Pair Repulsion Theory (VSEPR), the other atoms will seperate as far as possible, which results in bonds that are 109.5 degrees apart from one another. Sulfuric acid is an oxyacid of the element sulfur (S), based on the prefix "sulfur" combined with the suffix "ic". Sulfuric acid, or oil of vitriol, was used in the synthesis of the lapis philosophorum- the Philosopher’s Stone. Calculate the mass in grams of 3.65 molecules of sulfur trioxide. All the members of the same family (column) on the periodic table will have the same number of valence electrons. Clearly, Sulfur has a valence power of 6 and Hydrogen has only 1. Sulphuric acid may be prepared by catalytic oxidation of sulphur dioxide. Found inside – Page 102The zinc atom does not unite with hydrogen , but since it replaces the 2 atoms of hydrogen in sulphuric acid , it is bivalent . The matter of valence would be very simple if all elements had just one valence , but some of them vary in valence . The versatility of sulfur lies in its ability to take up numerous valence states, including -2, 0, +2, +4, and +6, and to form chain compounds and compounds in which sulfur atoms appear in more than one valence.
