Determine the oxidation number of S in the following sulfur-containing species: S033- Place your answer in the box Express your answer using only an integer number proceeded by either a + siu species with oxidation number of 'minus three". you should put -3 in the answer box. Note that there are no
The oxidation number of an element is the "charge" the element would have if all of its bonds were completely ionic; that is, if the electron pairs of each bond were transferred to the more electronegative atom. For monatomic ions the oxidation number is simply the charge of the ion. For covalently bonded elements the oxidation number is a bookkeeping device and does not mean that the element carries an actual charge. Determine the oxidation state for each of the...
