1. Few lenders now insist on taking a formal charge over a life assurance policy.

2. If the panel brings formal charges, Gingrich may be forced to step down as speaker.

3. So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.

4. So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.

5. So hopefully next time we do a formal charge question, we'll get everyone back up to speed.

6. So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

7. We haven't actually learned how to calculate the formal charge yet, we'll learn it soon.

7. Wish you can benefit from our online sentence dictionary and make progress day by day!

8. So what we see is that the formal charge on the nitrogen is 0.

9. To make a formal accusation or bring a formal charge.

10. So why don't you tell me what the formal charge should be on the sulfur atom of thionyl chloride?

11. So we end up with a formal charge on carbon of negative 1.

12. Authorities withheld the players' names pending the filing of formal charges.

13. Prosecutors plan to show that Martinez ordered several other murders-allegations that were never filed as formal charges.

14. So, we can also get into a case where we have similar values in terms of absolute values of formal charge between two different molecules we're deciding between in their Lewis structures.

15. And it does, so we know that we're probably on target in terms of calculating our formal charge.

16. For the carbon, we start with 4 valence electrons, we have 0 lone pair electrons minus 4, and we end up with a formal charge of 0.

17. The examples we've done so far have been pretty straightforward, so we haven't needed to use formal charge to make this kind of decision.

18. But I want you to tell me in terms of thinking about formal charge, which Lewis structure would you predict to be the most stable?

19. actually our third, but the second one we're going to talk about in terms of formal charge, which is thionyl chloride.

20. So, f c, I think you all know is formal charge.

21. So, these are the different ways that we can actually go ahead and use formal charge when we're choosing between different types of Lewis structures.

22. So now that we have enough practice drawing Lewis structures let's talk about actually figuring out this formal charge.

23. All right. So let's try one more example of drawing Lewis structures before we talk about formal charge.

24. And our eighth step in the process, again, is formal charge, which we will talk about very soon.

25. So we'll talk specifically about drawing Lewis structures and then about formal charge and resonance, which are within Lewis structures.

26. For the sulfur, we start off with 6 valence electrons, minus 4 lone pair electrons, minus 2, taking in account our bonding electrons, so we end up with a formal charge of 0.
