  2. How to calculate the formal charge of sulfate ion?

    chemistry.stackexchange.com/questions/4828

    FC = V − (B + N) F C = V − (B + N) Sulfate ion has two valid structures that you could draw, one with sulfur having a formal charge of zero and one with sulfur having a formal charge of +2. The structures below (from the Wikipedia page, released into the public domain) follow the annoying but allowable convention of replacing lone pairs ...

  3. Lewis Structure of SO2 - Chemistry Stack Exchange

    chemistry.stackexchange.com/questions/87057

    The formal charges of the SO 2 with the single bond and a double bond is larger than the SO 2 with two double bonds. So I would assume that the one with two double bonds is the correct structure. But chemistry books I have looked at (Zumdahl Edition 5 and 7) says that it is the opposite. Which is the correct Lewis Structure? inorganic-chemistry.

  4. How is (SO4)^2- Charged if S and O all are Neutral Themselves?

    chemistry.stackexchange.com/questions/39020

    As far as I understand $\ce{SO4^2-}$ structure, sulfur makes two coordinate bonds with two oxygen atoms and two double bonds are formed with oxygen after sulfur expands it's valance shell to 6. At this point calculating formal charge of those two coordinate bonded oxygen gives total formal charge of −2 and the formal charge on $\ce S$ and the ...

  5. Why does Sulfur have 12 valence electrons in the Sulfate ion?

    chemistry.stackexchange.com/questions/51012

    Sulfur has 6 Valence electrons, 2 in the first shell, 8 in the second shell, and 6 in the outermost layer (third layer). They can determine the number of kernel electrons and the number of valence electrons due to the bonds they form, for example Sulfur is more likely to form ions with the Alkaline earth metals and form different covalent bonds.

  6. Oxidation state of the sulfur atoms in the thiosulfate Ion

    chemistry.stackexchange.com/questions/24928

    Oxygen is (almost) always -2. To keep the overall charge -2, that means that the newly bonded sulfur is oxidation state +1. Oxidizing that sulfur again gives sulfurs of +3 and -1. Finally, in thiosulfate the oxidations states are +5 and -1. Yes, lewis structure does matter. Draw the lewis structure of thiosulfate.

  7. Why does sulfate have this structure? - Chemistry Stack Exchange

    chemistry.stackexchange.com/questions/5964

    Look at the structure for sulfate: Why does sulfur form so many covalent bonds. Its valency is only −2 − 2, it only needs two electrons, yet here it's getting 6 6. The same thing happens with phosphate. Phosphorus has a valency of −3 − 3, yet, it forms 5 5 covalent bonds. I think the key thing is that Sulphur can have a range of valencies.

  8. Sulfuric Acid - Bond Lengths and Charge Separation

    chemistry.stackexchange.com/questions/11033

    1) "So I know that the best Lewis Structure representation of sulfuric acid is one with only single bonds - i.e. sulfur isn't hypervalent. Look at the resonance structures below. The one on the left with sulfur hypervalent is the only uncharged resonance structure. I suspect that that counts for something. Here is a link that says it is the ...

  9. The terminal sulfurs, on the other hand, have no lone pairs, and all the electrons from the sulfur-oxygen bonds are assigned to oxygen, since it's the more electronegative element. The only electrons assigned to those sulfurs are half of those from the sulfur-sulfur single bonds. Hence, their oxidation state is: $$6 - \frac{1}{2}(2) = +5$$

  10. What charge is for sulfur? - Answers

    www.answers.com/chemistry/What_charge_is_for_sulfur

    Sulphur (also sulfur) is an element. It can be both uncharged and charged. In pure form sulfur is uncharged. As sulfide ions is has charge -2. In many molecules (like the amino acid custeine) and ...

  11. Can a sulfur atom form six single bonds with six other sulfur...

    chemistry.stackexchange.com/questions/127198/can-a-sulfur-atom-form-six-single...

    The next element to come to mind was sulfur because it was the next element that could form solely single bonds, fill its valence shell (by reaching into the d orbital), and have a neutral formal charge. So can sulfur atoms form 6 single bonds with 6 other sulfur atoms?
