Drawing the Lewis Structure for SO42-

Viewing Notes:

The Lewis structure for SO42- is requires you to put greater than 8 valence electrons on Sulfur (S). You would possibly think you've got the right kind Lewis structure for SO4 to start with. Remember, Sulfur is in Period 3 and can grasp greater than 8 valence electrons. You'll want to calculate the formal fees on each and every atom to you should definitely have the very best Lewis structure for SO4. You'll need to position a double bond on two of the Oxygen atoms so as to have the perfect Lewis structure. When you are achieved put brackets, along side 2-, round the Lewis structure for SO42- to show that it is an ion with a destructive two rate. SO42- has a complete of 32 valence electrons (understand that -2 price counts as two valence electrons).

Transcript: Hi, this is Dr. B. Let's do the SO4 2- Lewis structure, for the sulfate ion. On the periodic table: Sulfur, 6 valence electrons; Oxygen additionally has 6, we have now 4 Oxygens, multiply via 4; and those 2 valence electrons up right here, we want to upload those, as well. That offers us a total of 32 valence electrons. We'll put the Sulfur in the center, after which the four Oxygens will cross on the outdoor. Next, we will draw bonds between the Sulfur and the Oxygens, so there we have four bonds and we've got used eight valence electrons. Let's pass round the outer atoms and make sure they've octets. So now we have used 8, 10, 12, and 32.

Looking at the structure here, we see that each of the Oxygens has 8 valence electrons; 2, 4, 6, 8; as does the Sulfur right here, 2, 4, 6, 8. But we aren't moderately achieved but. Sulfur is in the 3rd period of the periodic table. That approach it can cling more than Eight valence electrons. So we in reality do wish to take a look at our formal charges. So to calculate the formal fee on the Sulfur: we see that Sulfur, on the periodic desk, crew 16 or 6, has 6 valence electrons. Up right here, all of the electrons, all of them are considering bonds, so that's going to be zero. And the bonding electrons, 2, 4, 6, 8; we now have used Eight of the ones, and we'll divide that by way of 2. Six minus 0 minus Four gives us a +2 formal rate for the Sulfur. For the Oxygen, it is also in group 6 or 16, so it has 6 valence electrons. Up here, nonbonding, we have 6; and then bonding, we have now 2. And some of these Oxygens are the identical, so we simplest wish to do one. Six minus 6 minus 2 offers us a minus 1 formal rate for each Oxygen. If we add up all the formal fees, the -1, -1, -1, -1 and +2, we do get a complete rate of detrimental 2. That does make sense, but with formal charges, we would like them to be as as regards to zero as possible for the atoms.

So let's examine if we would possibly be in a position to do any other Lewis structure that has more zeroes for the formal charges. When I see this +2 price right here on the Sulfur, I know that I can transfer electrons from the outer valence electrons of the Oxygen into the center. If I do that twice, if I move those two into the heart to form double bonds, and get rid of them, I believe that'll eliminate the certain 2 fee. Let's take a look at that and then recalculate our formal fees. So I've moved electrons from the out of doors of these two inexperienced Oxygens into the middle to form double bonds. Let's see how that adjustments the formal charges. So for Sulfur, 6 minus 0, there are not any nonbonding; and now we have 2, 4, 6, 8, 10, 12 overall bonding electrons. Six minus 6, that provides us 0. So the formal price on the Sulfur is 0.

If we have a look at the inexperienced Oxygens, you can see that we've got 6 minus Four of the nonbonding, after which 4 bonding; we divide by way of 2. Six minus Four minus 2 is zero. Finally, looking at the blue Oxygens, we've got 6 minus 6 nonbonding, and then 2 bonding divided via 2. Six minus minus 6 minus 1 is minus 1. So at this level, we see that we've got mostly zeroes. But in case you glance, you may have a unfavourable 1 and a unfavorable 1 right here. That works well with this. Since extra of the formal fees are 0, it is a better structure for SO4 2-. Since it's an ion, there is one last item we need to do. We wish to put brackets round it to turn that it's an ion and the charge of the ion. We add our 2 minus proper there.

And this is the Lewis structure for SO4 2-. It used to be a bit of of labor, however we have now the easiest structure here. Our formal charges are in excellent form. We've used all the valence electrons. So that's it. This is Dr. B., and thanks for watching.
