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 valence electrons are found on the valence shell, the outermost  shell of an atom.    By using the periodic table and the group numbers, one can find the  number â¦ of valence electrons for elements in groups (vertical  columns) 1-2 and 13-18.wo, two valence electron Oxygen has two valence electrons since it must gain two in order to obtain 8 electrons in its outermost energy level. However, the number of valence â¦ electrons is six--not two. The valence and valence electrons are only the same for metals in Groups 1, 2, and 3.
