Determining Oxidation States of Chemical Elements in Compounds

To determine the oxidation states of chemical elements in compounds, we need to consider the electronegativity and valence electron configuration of each element. Here are the oxidation states and names of the compounds you provided:

1. SF6 (Sulfur Hexafluoride): - Sulfur (S) has an oxidation state of +6 [[1]].

2. Na3N (Sodium Nitride): - Sodium (Na) has an oxidation state of +1 [[2]]. - Nitrogen (N) has an oxidation state of -3 [[3]].

3. CuCl2 (Copper(II) Chloride): - Copper (Cu) has an oxidation state of +2 [[4]]. - Chlorine (Cl) has an oxidation state of -1 [[5]].

4. PCl5 (Phosphorus Pentachloride): - Phosphorus (P) has an oxidation state of +5 [[6]]. - Chlorine (Cl) has an oxidation state of -1 [[7]].

5. N2O2 (Dinitrogen Dioxide): - Nitrogen (N) has an oxidation state of +2 [[8]]. - Oxygen (O) has an oxidation state of -1 [[9]].

6. LiBr (Lithium Bromide): - Lithium (Li) has an oxidation state of +1 [[10]]. - Bromine (Br) has an oxidation state of -1 [[11]].

7. MnO2 (Manganese(IV) Oxide): - Manganese (Mn) has an oxidation state of +4 [[12]]. - Oxygen (O) has an oxidation state of -2 [[13]].

8. H2S (Hydrogen Sulfide): - Hydrogen (H) has an oxidation state of +1 [[14]]. - Sulfur (S) has an oxidation state of -2 [[15]].

9. CaC2 (Calcium Carbide): - Calcium (Ca) has an oxidation state of +2 [[16]]. - Carbon (C) has an oxidation state of -2 [[17]].

10. MgO (Magnesium Oxide): - Magnesium (Mg) has an oxidation state of +2 [[18]]. - Oxygen (O) has an oxidation state of -2 [[19]].

I hope this helps! Let me know if you have any further questions.
