i just ran across a problem asking me to identify the valence electrons on a sulfur atom in a sulfate ion. my understanding is that sulfate ion = 4 oxygen + 1 sulfur atom and has a 2- charge. now, in the answer to this question, it reads: sulfur in a sulfate ion has 12 valence electrons, its original six... *which i was able to find; 1s2,2s2,2p6,3s2,3p4 plus 6 more from the oxygens to which it is bonded.
T here is no oxidation number for compounds, only the elements within compounds. The charge of SO4 (sulfate) is 2-. The oxidation number of each oxygen is 2-.The oxidation number of the sulfur in this compound is 6+.here are four oxygen atoms in each sulfate ion, so t â¦ hat the total charge from oxygen is -8. This means that the oxidation number of sulfur must be +6, so that the total charges will sum to zero, as required for a compound. 3 people found this useful. Rnp 279.
