@Maafa1619 Those aren't electron configurations. Those are the possible charges that chlorine can form by gaining or sharing electrons, called "oxidation numbers".
Thank god for this video. Taking Chem 1 in college. Listened to lecture, took notes,read book like 3 times and it wouldn't click. 3 Minutes in. Bam. It all makes sense.
My witch of a chem teacher gave us a quiz on the four differerent ways to configure electrons, and I got a 34 - _- I didnt understand how to do it, and shes giving our class another quiz on it tomorrow and this vid really helped me! :)
Excellent video! I'm not taking any chem classes but ive been very very intrigued with quantum physics, so this has led me to want to learn chemistry - all personal interest. I just started teaching myself biology as well, but when organelles in a cell are doing their things, it will help me to understand whats going on mechanically with chem background, so this tutorial helps me out. Thank you! With all the knowledge online, you don't even have to go to school to learn it! Beautiful :)
@MarkRosengarten Oh wow its not mandatory? I thought it was....so i can just put 3s^2,3p^6,3d^10..etc? not...the other way? Because i find it confusing to put 4s..etc..etc
Thanks so much. I loved your practical analogies and your enthusiastic approach. I spent an hour online trying to figure it out and still didn't get it. You did it in 10 minutes. Boo YA!
Thank you my teacher didnt really explain how he went from the electron configuration to the arrows and orbitals. I now know that you fill up every box then you do the down arrow! Thank you very much and you helped me understand now!
I mean like. God bless you and Chemistry. I was suppoust to take chemistry last year but the school was about to become an F graded because of the science FCAT(Florida Comprehensive Assessment Test) and the principal ordered everyone to stop what they were doing and start practicing for the test. Now I'm taking AP Bio and Anatomy, and I require a base of the entire Chemistry subject and now I'm completely lost.
Thank you for all your videos, I will learn from all of them
Can i just say your a life saver i just moved country and i had to do an entrance test and this is in it i havent learned so i watched this i have learned how to do it but i want to know is that " you say that PEL 2,8,18,32 but for calcium its 2-8-8-2 but in the test they just have 20 so how do i know to skip 10 electrons for the third PEL and instead just have 8
@Catarinaxo4 I find that even though I present it just like this in class, while watching it online you don't have all of the other distractions that go on in a class that take your attention away from the subject at hand and my students take a lot more time than just the duration of this video to "get it". It makes for a great supplementary lesson, though. Glad it helped!
how do you know the electron configuration ? I mean, in your project its already given under the atomic number but it's not given in the perodic table...any help please ?
If my question is not clear, you can see this picture : img696.imageshack.us/img696/3931/capturejru.png
I would just like to say thank you for this video. My teacher sounds like "Borat" when he talks and I have a hard time understanding in class. This video along with the powerpoints I already have, make everything "gel". I really appreciate it.
man thanks alot you saved me! my teacher explained this in class two weeks ago but I never got the hang of it but now seeing you explaining it in SIMPLE way ( a thing my teacher didn't do)Ive finally understood it
See this helps a lot,considering my teacher never actually teaches since my class is all out of control,since most of them know this already since they are all the smart egotistical type.So I never learn and then finals come along and I'm fucked,especially this year since I missed the two days she actually taught this, and I was out with pneumonia,so I asked for help,she didn't explain anything and gave me a shit load of papers I had no idea what to do with.Finals are here for me and I'm fucked.
i am learning this in my chem class.. however, in order to lets say give the electron configuration for oxygen, would you need the chart to identify what goes in what sub levels? such as s,p,d,f?
My teacher doesn't really explain the basics and just jumps around. Thank you for clarifying the basics of electron configuration. Your a great teacher.
very well done! I really appreciate how you can be happy while teaching this. I was out of school the day my AP Chem teacher taught this and I just couldn't pick it up from my book. Unfortunately, I didn't remember how electron configurations worked from my previous chemistry experience either. You really made a difference for me and I appreciate that you took the time to teach this! Thank you!
thank you so much man, you dont know how much you've teached me. my teacher has been teaching that for like a month now and i still dont get it and in 10 mins i got it. thanks again. Take Care.
my teacher is so crap he is from east London and has a huge gold watch, and when he explains something he says 'do u understand' each time and then smiles at you as if u understand and then i just smile back but dont know what is going on.
Can you please explain to me why Cr24 has only one electron it it's 4S orbital? Does something specific happen as soon as you hit the 4D orbitals :S cause i think i missed something in class and now I'm very confused, please help. Thanks :)
My best guess was that Cr24 has this configuration... 4s1, 4p1, 4d4. But then i get confused as to what orbital will be filled first and which last :S
hmm.. you wrote 1s 2s 2p 3s 3p 3d 4s 4p, but when I look at my textbook, it says that it should be written as 1s 2s 2p 3s 3p 4s 3d 4p instead, am I misunderstanding something here? =/
OMG, I learned more from him than my new teacher since last week! All my teachers says is "they have two spins"... -I look at him wondering what the hell he meant in silence while he looks at me with the "what are you looking at" face- ... >> Whole class was like that too.
I have learned so much here. Am I meant to be learning this at GCSE level? Now I know so much more about this than anyone in my class :D Taught so so so so incredibly well and that's coming from an english girl who is a little bit proud of her english origins and consequently, quite opinionated.
Wow I should seriously reconsider my basic and very udgemental/stereoptypical principles that these people are all stupid and fat - i blame the crappy movies for portraying you guys this way. CHEERS!!!
@burtv1610 Yeah...I had a bit of a jelly bean problem when I was younger. Plus, my whole family has weight issues, going back generations. Believe it or not, I was a string bean in high school! But one thing I like to think I'm NOT is stupid. :) Glad to be of assistance!
@kik0chan Nope...2 = 1s2. 7 = 2s2 2p5. The basic configuration gives you information about PRINCIPAL ENERGY LEVELS, where the expanded configuration breaks them down into SUBLEVELS.
Thanks. That finally made sense to me and I have a test tomorrow. You look like the cop from supertroopers that wanted a liter of cola. Chickenfucker! :)
I have had such a mental block with Chemistry and I'm 44yrs old. I want to become an RN and was beginning to feel as though it would never happen, there is gonna be that certain someone out there who all of a sudden will put it to you in terms that you can suddenly grasp...don't give up just keep on keeping on.
i wish you were my teacher! This was more helpful that 4 weeks of lecture at my university... needless to say my teacher sucks a fat one. All he cares about is his research.
This is not the best explaination I have come across. This professor is really easy to understand for me, although, my professor will not let our class have the amount of electrons in each orbital on our periodic table (For example: for Sulfur 2-8-6). The explaination of the periodic table with the shells(period number) and subshells(sections) is easier when you do not have this video's periodic table.
@AFourMteenA I teach this with the New York State standards and Reference Tables in mind. There is the diagonal rule that takes care of everything...but when you are dealing with transition metals, the rules don't necessarily apply.

@AFourMteenA I teach this with the New York State standards and Reference Tables in mind. There is the diagonal rule that takes care of everything...but when you are dealing with transition metals, the rules don't necessarily apply.

@AFourMteenA Makes sense.

This is not the best explaination I have come across. This professor is really easy to understand for me. Although, my professor will not let our class have the amount of electrons in each orbital on our periodic table (For example: for Sulfur 2-8-6).

What is the maximum number of electrons in the 5th level? In your example, "I" has 7

@pyocote 2-8-18-32-32-18-8 lists the maximum number of electrons in each shell.
