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.
The sulfate or sulphate (see spelling differences) ion is a polyatomic anion with the empirical formula SO 4 2â . Sulfate is the spelling recommended by IUPAC, but sulphate is used in British English. Salts, acid derivatives, and peroxides of sulfate are widely used in industry.Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid.he sulfur atom is in the +6 oxidation state while the four oxygen atoms are each in the â2 state. The sulfate ion carries a negative two charge and is the conjugate base of the bisulfate (or hydrogen sulfate) ion, HSO 4 â , which is the conjugate base of H 2SO 4, sulfuric acid.
