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 stock system gives the actual charge of the ion What is the difference between the anions sulfite and sulfate? The sulfite ion has one less oxygen atom than the sulfate ion How many atoms make up the oxalate ion and what is its charge? It is made up of 6 atoms *2 carbon and 4 oxygen) and it has a charge of 2- What three hydrogen-containing polyatomic anions are essential components of living systems? 1. hydrogen carbonate ion
