My chem teacher couldn't explain Lewis dot structures in one hour & 30 mins. You were able to explain everything that I need to know in 8:38. I love you.
you are helping me pass Gen Chem 1!! Thank you so much!!! Suggestion: Can you make videos where you have a few sample questions within the first few seconds, allow us to pause the video, and then press play to watch you go through the solution? That'd be most helpful. Keep up the good work. i'll be leaving your video information on my professor's end of semester comment card.
Have an exam tomorrow, instead of spending near an hour on the topic it just took 8 minutes. And since I have many topics and left study to last second, I am saved thanks to you!
wow...you are the best! I was really struggling with lewis structures and was losing all hope in understanding it. But you explained it so well and straightforward and in simple terms. I have a chemistry test anymore and this helped me :) thank you so much!!!!
Just a quick note, when she goes over the second resonance structure of SO3, I think that the one that has the double bond needs to have two dots removed like in the first resonance structure.
The second example of a resonance structure had four more ve-s than needed. Those were on the double bond. Since one of the O molecules is sharing two ve-s, only 4 are needed. Just a clarification for anyone who was thrown off by that. Otherwise, keep up the good work! You're cool!
@brightstorm2 I rarely take time out to comment on videos especially now that i'm cramming for midterms but just wanted to thank brightsorm2 for all these beautiful videos :D
Taking an entry level Chem course at College right now. The teacher is horrifically unorganized and not great at explaining at all. Thanks for teaching me for free what I paid someone else to do!
Amazing teacher you summed up everything i need to know for my exam tomorrow in 8:38 secs and made me understand! It took my teacher weeks and i still didn't understand!
For CS2. Take 3 multiply by 8 which is equal to 24. Then take 24 and subtract by what they actually have which is 16. Take 24-16=8. 8 Translates to the following a triple bond or a single bond or two double bonds. And you have the # of bonds.
I think you added an extra electron pair when you drew the resonance structure for SO3, around the double bonded oxygen you have three pairs instead of two
For CN-, it has 2 atoms. Multiply that times 8 and that gets you 16. Take 16 and subract with what it actually has which is 9 for the electrons +1 for the minus charge. 16-10=6. 6 means there is a triple bond.
You explain this very well for those of us not majoring in chemistry.When I go to MIT site, I get so confused. Thank you for dumbing this down for me! :>) lol
Sorry, the resonance structure you drew at 7:05 has an extra lone pair on the oxygen that should not be there since you used it in the double bond. Awesome video! Thank you!
If you take the number of elements in the compound, NF3 which is 4. Multiply that number by 8. That comes out to 32. Subtract what they actually have which is 26. That says there are 6 electrons which translates to 3 bonds. Then you just draw the other 26 out.
Usually you learn the trends of electronegativity on the periodic table; it increases across a period from left to right, and decreases down a group. When comparing atoms, it's usually quite simple to see which is the least electronegative. For example you know that carbon is less electronegative than nitrogen because they are in the same period, but carbon is to the left of nitrogen. Similarly, nitrogen is to the left of fluoride hence it's less electronegative.
Thanks a lot. Your way of figuring the atomic number is much easier than my instructor's way. She is like count all the way to the element, and do electron configuration and finally count the valence electron from the octet shell .
I love your video explanations they are fantastic! I will probably reference them when I teach! I just wanted to mention in your resonance explanation when you drew the second dot diagram, you put the double bond on the middle oxygen and then you added 6 more electrons around it making it have 10 total. I wanted to clarify in case that confused anyone!
thank you for a nice video. I have a question about the resonance stuctures. The one you wrote on the right side of the arrow, the oxygen atom with the dobbelt bond has 6 electrons around it as well, do we see a minor mistake? shouldn't two electrons (dots) be removed when creating the dobbelt bond?
Sulphur is group 6, group 6 is -2 (plus two electrons), Carbon is period 4, period 4 either gives/takes/shares 4 electrons, ergo Sulphur has a greater negative charge. This is from what I understand, could be wrong...
It is more electronegative, meaning it has the tendency to have the larger share of the valence electrons since it would spend more time orbiting around it. Hence, why she put them on Nitrogen first but unlikely that this would help you since you posted that 4 months ago but oh well
Nitrogen is located on the right side of the periodic table, thus being a non-metal. Take a look at a number periodic table on google, and notice how Nitrogen is in group 5 or group 15. What matters is the "5" which represents the amount of electrons Nitrogen holds in its outer-shell.
@faisalshafique830 The electrons don't orbit around the nucleus because of Wave-Particle duality. Electrons are sometimes waves, and sometimes particles. Therefore we have orbitals instead (nothing is orbiting, orbitals are only probability functions which determine the area in which 90% of all electrons are likely to occur). There is no way of determining the exact position of the electron. I suggest you look up Hund's Uncertainty Principle.
@Spirit0fTheWolf1 LOL, yeah. My mid terms began on the 12th, starting with my AP Physics Exam, then on Friday I had my Honors Precalc and AP English, then My AP US History and Chinese, and last but not least my 2.5 hour long AP Chemistry exam which is tomorrow. Wish me luck.
Great video. I don't know why it has taken me so long to see it explained so clearly and simply. Great job.
My chem teacher couldn't explain Lewis dot structures in one hour & 30 mins. You were able to explain everything that I need to know in 8:38. I love you.
Wow very well articulated! I could definitely understand every word you were saying because you were talking at a very nice pace!
you are helping me pass Gen Chem 1!! Thank you so much!!!

You have no idea that you just save my life, I wish I could replace my chemistry teacher and have you instead. Thankyou
Hahaha wish can do that?
oh my God!!....she just takes the most complicated topics to floor level...you are God sent!!
This teacher deserves a medal! Thank you.
I'VE LEARNED MORE IN THIS VIDEO THAN I HAVE THE WHOLE SCHOOL YEAR!! SCIENCE RULES!! I LOVE YOU SO MUCH. LIKE REALLY, A LOT. :)
not only did you help me understand this concept but i think i also love you, great job thanks so much
Have an exam tomorrow, instead of spending near an hour on the topic it just took 8 minutes. And since I have many topics and left study to last second, I am saved thanks to you!
wow...you are the best! I was really struggling with lewis structures and was losing all hope in understanding it. But you explained it so well and straightforward and in simple terms. I have a chemistry test anymore and this helped me :) thank you so much!!!!
Thank you so much!
I have watched your videos along side my study and these are what have made everything clear to me! Wonderful!
I watch all of your videos....wish you were my teacher because i do all my learning through your videos! Thank you!
Thanku soo much u r the perfect teacher....
God bless u and ur family
Im very very Happy, that someone posted This very helpful videos... THANK YOU!!!
Just a quick note, when she goes over the second resonance structure of SO3, I think that the one that has the double bond needs to have two dots removed like in the first resonance structure.
I must say that you are truely amazing.. you make more sense to me than my professor!!
I always love how you explain things. Thank you. Makes life easier.
with a teacher who doesn't teach, her video is saving my life for my test!
Amazing, so so helpful. This should have more views!!
The second example of a resonance structure had four more ve-s than needed. Those were on the double bond. Since one of the O molecules is sharing two ve-s, only 4 are needed. Just a clarification for anyone who was thrown off by that. Otherwise, keep up the good work! You're cool!
nobel prize winner here! best teacher ever!!
THANK YOU!!! For making this so simple!!! Between my book and professor I thought I would never get this...this makes complete sense :)!!!
I'm amazed at how fast you're doing those structures.
Getting through college chemistry thanks to you!:)
@brightstorm2
I rarely take time out to comment on videos especially now that i'm cramming for midterms but just wanted to thank brightsorm2 for all these beautiful videos :D
I love this woman. She helps me so much.
Thank you. I understand it better now, and I'm ready for the next exam.

Thank you very much!!!!!
Finally I understand it after many of hours for trying to understand....
thanks to you, i'm actually understanding this concept!
thank you so much! this is definitely going to help in my HL chemistry test tomorrow! :)
I've watched 3 youtube videos and FINALLY UNDERSTOOD!
For CN-, it has 2 atoms. Multiply that times 8 and that gets you 16. Take 16 and subract with what it actually has which is 9 for the electrons +1 for the minus charge. 16-10=6. 6 means there is a triple bond.
best video so far, thank you god.
you're really good at explaining! thanks!
Beautiful! I really wish that you were my chemistry teacher... that would have been an A for me.
You explain this very well for those of us not majoring in chemistry.When I go to MIT site, I get so confused. Thank you for dumbing this down for me! :>) lol
east or west brightstorm is the best !!!
Holy shit after my teacher going over this for a week you helped me understand this in 10 minutes thank you so much
Sorry, the resonance structure you drew at 7:05 has an extra lone pair on the oxygen that should not be there since you used it in the double bond. Awesome video! Thank you!
"Don't worry Carbon, I'll take care of you. I will bond with you."
:]
Thank you so much for clarifying this subject for me, it has been so helpful.
thanks allot my exam is tomorrow and you just made me understand the whole thing
how'd it go?
as clear as can possibly be, you've got yourself a subscriber
Thank You SO Much!!!!! You are simply amazing and have helped BIG TIME.
If you take the number of elements in the compound, NF3 which is 4. Multiply that number by 8. That comes out to 32. Subtract what they actually have which is 26. That says there are 6 electrons which translates to 3 bonds. Then you just draw the other 26 out.
excellent explanation. To the point. Love it.
i finally undertsand! thank you so much :) i like your methods on doing it, it has really helped, my chem exam is tomorrow though D: but thanks
thanks, I was having trouble with this, but it was well explained
this video helped a lot! bur how would u do the structure for metals such as Cu?
i love you. you made this so easy to understand.
GREAT EXPLANATION CHEERS!

this is very helpful if teachers explained like this it would make life much easier
MVHS
This was amazingly helpful ! I wish I had watched this one first ! :S
If I am following correctly, during the example of SO3 there was not supposed to be 6 electrons drawn around the double bond.
Thanks a lot. Your way of figuring the atomic number is much easier than my instructor's way. She is like count all the way to the element, and do electron configuration and finally count the valence electron from the octet shell .
Thanks for the wonderful explanation!
If only they had entire classes boiled down to youtube videos like this. She basically explained everything you need to know.
Atoms are so NICE to each other when they bond!!! :)
Thanks it's much clearer to me now...
You Are An Awesome Teacher
I love your video explanations they are fantastic! I will probably reference them when I teach! I just wanted to mention in your resonance explanation when you drew the second dot diagram, you put the double bond on the middle oxygen and then you added 6 more electrons around it making it have 10 total. I wanted to clarify in case that confused anyone!
Your videos are helping me so much thank you thank you thank you!!!!
Omg I totally understand how it works now. Thank you so much!!! You're a life saver :)
thank you for a nice video. I have a question about the resonance stuctures. The one you wrote on the right side of the arrow, the oxygen atom with the dobbelt bond has 6 electrons around it as well, do we see a minor mistake? shouldn't two electrons (dots) be removed when creating the dobbelt bond?
I signed in just to like this video because it was really helpful for my chem h/w
Thank you so much, You make so much sense!
Well explained... Do continue to post more videos....☺☺
Thanks! this helped me so much!
Amazing video! I learned a lot!
@ 7:30 the second diagram is wrong, there should be 4 dots on the bottom oxygen, not 6
Sulphur is group 6, group 6 is -2 (plus two electrons), Carbon is period 4, period 4 either gives/takes/shares 4 electrons, ergo Sulphur has a greater negative charge. This is from what I understand, could be wrong...
It is more electronegative, meaning it has the tendency to have the larger share of the valence electrons since it would spend more time orbiting around it. Hence, why she put them on Nitrogen first but unlikely that this would help you since you posted that 4 months ago but oh well
i just had a major epiphany. thank you so much.
genuinely learned more about this in 8 minutes than i did in 80 minutes of class.
Thanks for this perfect explainations!
Nitrogen is located on the right side of the periodic table, thus being a non-metal. Take a look at a number periodic table on google, and notice how Nitrogen is in group 5 or group 15. What matters is the "5" which represents the amount of electrons Nitrogen holds in its outer-shell.
Thank you so much! I finally understand this now! :)
thank you for clear explanation.
This is very helpful, Thank you very much!!!
That was very helpful. Thank you very much
SIMPLY THE BEST TEAAAACHER EVEER !!!!!!!!
Thank you so much! Without youtube, I wouldnt stand a chance against chem 102 :p
Great explanation !
She should talk about how some elements can have an expanded octet
@faisalshafique830 The electrons don't orbit around the nucleus because of Wave-Particle duality. Electrons are sometimes waves, and sometimes particles. Therefore we have orbitals instead (nothing is orbiting, orbitals are only probability functions which determine the area in which 90% of all electrons are likely to occur). There is no way of determining the exact position of the electron. I suggest you look up Hund's Uncertainty Principle.
thank you, that was so relevant
perfect teacher thanks so much
Thanks, this video was helpful.
thank you! this was really helpful.
amazing video learned so much
Good explanation👍🏻^_^ thanks.. Anyway I hope to know more about expanded octet..
Wow......... Amazing Teacher
very helpful! I wish you were my teacher!

could you explain how you would raw the diagram for KICl4?
