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.
ow many more electrons can fit within the valence shell of a fluorine atom? 1 How is the number of unpaired valence electrons in an atom related to the number of bonds that the atom can form? The number of unpaired valence electrons in an atom is the same as the number of bonds that the atom can form. Why is it so easy for a magnesium atom to lose two electrons? Because magnesium has only two electrons in its valence shell.
