Great video. This really helped me, and I will use it on my Chem midterm tomorrow.

[cassiieecake92]

Thank you! Your video helped me study for a test and made the material more clearer than how my teacher explained =]

[Ivorykeystease]

Thank you! This helped me understand it more for my final Monday.

[ehil13ily]

Thank you! I appreciate you taking the time to make videos like this. I learned more from this video than I did in my 50 minute class period. 

[7328nessa]

what are magnetic quantum numbers?

[whitwellhigh]

@7328nessa .... basically the numbers that are supposed to represent the number of possible orbitals in a for a particular orbital.

[JermHD]

YouTube is the Terminator of classroom lectures!

[kielymawiee]

"i'll stop at 10 'cause this is gettin crazy!"

so many good things about this video

[how2backtrack]

Thank you sir, your 6 minute video taught me quantum numbers more clearly and effectively than my 50 minute class.

[gvsfgdf]

A little tid bit.... The Quantum Numbers arise from the solution of the Schrodinger's Equation..... They must have discrete values for the complex Fourier series solutions to make sense :)

[username6333]

Thank you for making this video.

[gabi44w]

Just making sure, but isn't the orbital quantum number also the angular momentum quantum number?

[whitwellhigh]

@gabi44w - angular momentum quantum number = second quantum number (L - a lower case L) = azimuthal quantum number.

[the4567]

thank you 

[MrChampHunter]

im in ap chem it sucks...thanks so much this was a huge help

[360MrCarter]

its spelled principal(principle in your video) in my text book, which one is correct way of spelling principal quantum number?

[whitwellhigh]

@360MrCarter - I was always told...that Principal...was for a school....and use the other one for other stuff.....However, you are correct....in the text books....it's principal quantum number.....Old Elementary Rules die hard LMAO....I goofed on that one LOL

[360MrCarter]

@whitwellhigh thanks for you for thereply to clear the confusion and good video to help people understand quantum numbers better.

[waltradam]

thank you!!1

[SuperLINKme]

hey, thanks for the vid.

i posted this just yesterday in our group in facebook for our assignment. each of us watched it... the next morning the whole class actually participated in our chemistry period.

thanks alot! luvlots!

[fyeahsupernova]

ummm where did you get the numbers like 0 1 2 3??? i dont get it

[whitwellhigh]

@fyeahsupernova --- the principle quantum numbers (n) start with [1,2,3,4,5,6,7.........} and the possibilities of the orbital quantum numbers (n-1) is [0,1,2,3,4,5,6,.......] basically your orbital quantum numbers must always be smaller in value to your principle quantum number. s orbital has a value of 0....p orbital a value of 1....d orbital a value of 2.......f orbital a value of 3......and so on

[therealjordiano]

3:27 thank you :D and for the rest of the vid too lol, epic teacher :)

[CfergSPSU]

@whitwellhigh ok thank you...that actually made sense lol

[CfergSPSU]

how do you know if the spin is positive or negative?

[whitwellhigh]

@CfergSPSU - its basically like this...electrons enter into an orbital with a spin (unkown)...but the other electron in order to enter that orbital must be opposite in spin....thus the values of +1/2 and -1/2 are used...think of it as the orbital just having 1 electron in it being half filled (like half filled like a shoe box with one shoe)...i can send you a link detailing more exact scientific reasoning....but the concept I have explained here is only basic CONCEPTUAL understanding.

[theskiper241]

@CfergSPSU Due to the Aufbau Princple, that says An electron occupies the lowest energy orbital that can receive it.

[whitwellhigh]

@theskiper241 - good Kung Fu :)

[theskiper241]

@whitwellhigh what?

[nupsyyy]

You really should have told what does these signifies and what does these mean.

[whitwellhigh]

@nupsyyy - watch the other videos and you will see :)....cliff hanger lol

[chuahuaha]

Thank you for making it so much easier to learn!

[whitwellhigh]

@aNaRcHyFoReVeR4 - good point...but it does not take a scientist to tell you why dog poop stinks....we just simply understand why it stinks....simplicity is often left alone because of common sense, but i simply made these videos for my students"the WHY was explained in class" they simply just come here to watch the how.If GOD gave us all the answers and all the WHYs every moment we have ever asked him, we would never look or reason for ourselves. FREE WILL. Open your mind and your Book :)

[bourdvi]

I have to say I am glad to hear someone explain the concept in a more simple way, now you should explain that even though we do know 118 elements (which 110-118 are instantly formed and for a fraction of a second) it is almost impossible to move to an element that has I and so on since the amount of room between the electrons are so small that the would practically hit each other. easy example to show would be the placement of the electrons with the S,P,D, F orbitals to show the room in between

[whitwellhigh]

@bourdvi - very good idea...and I really do need to do one....and thank you.

[bourdvi]

@whitwellhigh very welcome. taking grade 12 chem this year and landed on ur video, quite accurate and precise. a good way to show it would be with a row with the different orbitals where u can show hows the order goes.

[domeymcsquire2]

"I'm gonna stop at ten cuz this gettin' crazy!" lol

[mblack1001]

"Four, five, SIX orbitals!"

"Seven, eight... NINE ORBITALS... AH AH AH!"

[TrendSettingDJ]

You're the man. Thank you for this. There was another guy on YouTube who was also good, like yourself. ChemGuy (bananaiscool) - then he began charging for his videos. I hope you never feel the need to do that. Keep up the good work. I like your stuff better than khan academy.com

[whitwellhigh]

@TrendSettingDJ - thank you...means a lot....no my videos will always be free on here :)

[ryandsz]

@whitwellhigh you are currently saving my ass... thank you sooo much

[whitwellhigh]

@ryandsz - I am glad to know that :) lol

[chikaprz89]

who needs school; I HAVE YOUTUBE :) HAHAH;

thanks for the help :)

[brennanx8]

My teacher never even used the periodic table to help us understand the orbitals... I want to love chemistry (science), but my teacher is absolutely horrible.

[whitwellhigh]

@brennanx8 - i honestly....do not see how you could teach or even explain orbitals with using the periodic table.....WEIRD!!!!!!!

[a192589]

why did it take my teacher 3 class days, which are each nearly 2 hours long, to explain something so simple....?

ugh i hate bad teachers -_-

[whitwellhigh]

@a192589 - even I may not always explain everything perfectly....However, all I care about is students not being scared of chemistry :) ....... sometimes.......we may explain or say something incorrectly just to simply.....the topic or subject.... (forexample).....i was so carried away...in my over simplyfiing the concept....that i missed spoke....about the LETTER J lol....opps....However, the concept is that easy LOL

[asifbliss]

@a192589 word to that! i can relate lol

[Regards200800]

@a192589 it took my teacher 7 classes, 40 minutes for each class, and he doesn't even know how to explain it... that's what got me here.

[whitwellhigh]

@Regards200800 - i hope my examples, problems, and videos are helpful to you and everyone else....To all the serious chemistry teachers out there....i am sorry i am over simplifying this....but over all it is an easy concept LOL....That is the type of chemistry I am.....I try to allow students to love science and not hate it (with eyes rolling into their heads) LOL

[Roflshamans]

Thanks. A lot better than a useless textbook that just smashes you with walls of mindless text.

[mephatboi]

u're the 1st person ive come across who explained "n" simply in terms of the row #

[sonofaimran]

good video.... lol " I'ma' stop at ten, cause this is gettin crazy.."

[whitwellhigh]

@sonofaimran - man going past 5 is crazy too LOL

[rararCharizard]

Much easier to understand compared to my Chem Professor! Thanks!

[whitwellhigh]

@rararCharizard - thank you.... user: s6e6r6r6a6t6h is right that the letter (j) should not be used....I did get carried away with my alphabet LOL.....s,p,d,f,g,h,i (L=0,1,2,3,4,5,6)....is normally all you will ever be asked about by an undergrad chemistry professor :)

[Godofrockl666]

Thanks

[misato56]

thank you! ^_^

[s6e6r6r6a6t6h]

"j" should be omitted in lettering orbital angular momentum states.

[whitwellhigh]

@s6e6r6r6a6t6h - i believe that you are correct....because the quantum number j represents the total angular momentum describing Russel-Saunders coupling.......I was just trying to show a connection of the types of orbital and their connection to the orbital quantum number....sorry that I spoofed and goofed on the comment and labeling.....shame shame on me LOL

[whitwellhigh]

@whitwellhigh - i know...i feel asleep that day.... LOL

[rachelk1991]

the 4 dislikes are probably from humanities students

[Buurlits]

Thank you!!!! i have exams tomorrow and this is the topic!!! thank you for uploading this videos!!!! :P

[Mejiera12]

lol

[airsoftsniper33]

my buddy goes to whitwell high

thank you for posting! very helpful =)

[TheCj383]

helpful vid.



[whitekaminari]

yes sir, it helps!

[jtbmilan]

Thank you johnny cantrell!! i got to study in advance because of this video :)

[celostina08]

THANK YOU SO MUCH SIR, YOU ARE GREAT!

[slwilli7]

You sir are truely sent from up above!! Thank you for uploading these videos. You have no idea how you much you are helping me. Please dont stop, this is amazing and I just wanted to let you know, I am so thankful to you for helping me understand what i could not!!

[roushangar2006]

Good Job!

[Sickhism]

Thank you for the upload yes it did help! summarised an hours reading in 6 minutes

[DRoger90]

You are awesome this was very helpful! Question, you said as L goes up, the letter changes as well. Ex L(5) = h, L(6) = i and so on, what would you put when you got to L(13) = p when there is already a "p" orbital?

[whitwellhigh]

@DRoger90 - I will be honest....the highest L value I had to ever determine as a professor/teacher/student was an L value of 10.....But, if I were to use logic....It should just be p....but that would be stupid...LMAO....Therefore....­I am like you....I would have to look that one up or ask a college...but generally questions about L do not exceed 10.....Unless your professor or teacher is crazy... :) However, once you find out.....Let me know too :) and your welcome :).....

[shadesofgreyy]

So helpful! Thankyou so much!!
