Quantum Mechanical Model

007 - Quantum Mechanical Model
In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the position of the electron is determined through quantum numbers.

Thank you very much for posting this! I learned the shell method years ago and am now taking chemistry at a higher level, and the news that the shell method is no longer in use blew my mind. Very well explained :)

[@horsebiscuityt6135]

This is actually THE MOST useful video ever... wraps all the concepts I'm learning about into one comprehensible video. Thank you VERY much for this!

[@cartersmith1660]

I’m an 8th grader doing a presentation on the work of Erwin Schrodinger and that was a fantastic video. Even though I am 13 you made it easy for me to comprehend an extremely difficult subject.

[@janaamr7390]

yeah man, you are right. I love the way he explains. I am 15 and it was super clear to me.

[@arneshpal7702]

8th? Nah 💀💀

[@yvngrxxd9078]

bro im learning abt this in the 12th💀💀back in 8th we were playing clash of clans in class

[@prabhjotsinghkainth2282]

Better than my chemistry teacher

[@prmbiy]

+PrinceCrazy way better

[@thomascurrie5311]

+PrinceCrazy savage

[@seanderesh7192]

Same

[@hnurtanic]

Absolutely

[@Mrsthallium]

Why are chem profs so universly awful?

[@angelakrim3326]

I have to write a paper on the history of the quantum mechanical model of the atom, and I wasn't able to do that because I didn't even understand the quantum mechanical model! Thank you for the clear explanations- it helped a lot!

[@taaptee]

These videos are great for revision, and understanding topics better, thank you!

[@kaitshipp12]

Thank you so much! That was extremely helpful. I'm comparing the Bohr model then reading in to the Quantum Mechanical model and got lost around quantum numbers and came running to youtube. Thanks for coming to the rescue.

[@rbtwithme7455]

Same

[@sarahtasneem6654]

Thank you m
Thank you Mr.Paul, this is amazing. I hope we all can score with flying colors!

[@kaylachristined]

I am so grateful for these videos!! Thank you damn I understand what I couldn't from my prof or the textbook

[@zazzlefrass1125]

This video helped me understand the basic concept a bit more, but I still need more information on how n, l, and ml interact. If you already have a video explaining that, a link to it in this one would be nice.

[@jamesthecreator4263]

Thank you for your videos, they are very helpful!

[@TheMrShrewd]

thanks man. i appreciate. keep making stuff

[@LargePonyStep]

thank you sosososo much mr. andersen!!!

[@canadianhaitian]

Very well explained! That's it i'm done going to university and leaving clueless and confuse. You TUBE HERE I AM!! Where can i give donations because you guys ROCK!!!!

[@eligomez333]

nonetheless, I actually learned what ive been reading and not understanding for 2 days. Thank you for doing these videos!!

[@DiamondMind]

Thanks! Appreciate your videos.

[@muichiro1978]

The most helpful channel in the world.

[@hadeerrashad3497]

Your explanations were so helpful thank u so much.

[@ms_xilu]

10 YEARS AGO DAMMMMMM, tysm needed this!

[@averagebeast99]

You just earned another sub

[@Daenysthedreamer287]

Thank you. My textbook is horrible. :'( and we don't even have lectures either...

[@rurichek1]

So the orbital is a sphere where the electron might be present? Is the nucleus right in the center where x and y intersect?

[@antonio-ry9tc]

my chem prof really was out sick for 2 weeks and is making us take a test on this and our final on the same day rip me

[@francoisungerer2727]

Great video. Thank you! :)

[@kaylanealmeida8491]

i'm from brazil, i understood everything just with your class, thanks!

I am Indian

[@dmncm3887]

Much better than crash course

[@hanaescovar8997]

You should include the script of the video in the description :D

[@polette7soto]

Could you please make one on organic chemistry

[@ketakipandey807]

seriously man video on schrodinger n heisenberg's principle neede....:) :( :))

[@harshanarukmal9895]

atom or any other particle is a rotating and revolving frequency. great video. please concern about my opinion also about atoms. universe = rotation

[@mharfrein.7806]

what does the "n" refers to in the quantum mechanical model of atomic structure?

[@Benjuthula]

Helpful indeed. Thanks.

[@jamilehassan4902]

Thank you I enjoy your presentation

[@sk.chandbasha2777]

well explained.

[@shezaag1171]

Wow! So concise!

[@TipoQueTocaelPiano]

Did you mistake the uncertainty principle for the observer effect?

[@HALOUNSC2552]

007 I see what you did there.

[@ketakipandey807]

ty for dis one..!!!

[@niteshdubey5828]

Sir you are a great man.

[@ericahertzberg9390]

this guys awesome!

[@arefhamaoui9962]

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

[@joumanaswailem6245]

you are amazing I wish my teacher knew how to explain like you thankyou

[@leegwenbolibol7140]

I Study at Sarrat National High School (SNHS)....Our teachers has their own techniques to share to us and its also makes our lessons more easily to understand and they dont depend on books...

[@jullaangela2780]

Thank you very much!

[@danielmacarthur8478]

Thank you sir

[@kyankaizer1313]

tnx guy u helped me a lot I passed my exam

[@berni1602]

Please, please, make one about Heisenberg's principle.

[@locsavaric2310]

I'm no professional or anything, just comparing your explanation of the uncertainty principle with other sources. Others say your explanation described more the "observer effect" whereas uncertainty is inherent in quantum matter...is this a significant difference?

[@melissamiller5069]

QUANTUM NEEDS TO BECOME OCTIVES FOR THEY FOLLOW SOUND FREQUECIES SAME AS MUSICAL NOTES AT DIFFERING PICHES?

[@terra69]

Our class was boring so I'm watching this.

[@amandadavis5311]

very helpful

[@Missdarkwinter]

Thank You

[@sanketdongare2606]

Sir really very good👌👌👌

[@xanguto]

Suggestion: there are many people in different countries trying to understanding the structure of an atom. In my native language for example, there is no a good video that provides a clear explanation about it. So, if in the next video you can speak not so fast we would be very greatful. Anyway, thanks because the explanation is good.

[@fatbelliesilike1680]

Why did neon have 11 protons though???

[@manojjoshi939]

do electrons actually spin around an axis?? if not why a spin quantum number?

[@TMPChem]

Hi Manoj. The short answer is "we don't know". The most precise experiments today have as of yet been unable to estimate a lower bound for the radius of the electron. Every time we zoom in closer, the electron continues to appear to be a point particle with no internal structure. The current estimate for the *maximum* possible size for the radius of the electron is 10^-18 meters, or almost a *billion* times smaller than the atom.
Mathematically, the electron's spin angular momentum looks the same as any quasi-spherical object rotating around its axis, but we're not actually sure there is an axis, and it doesn't appear to be directly analogous to classical rotation. With an electron's mass and upper-bound radius, it would have to be spinning far faster than the speed of light to have the observed spin angular momentum. All we know for sure is that spin angular momentum of electrons exists, is unexplained by classical models, and is very weird.

[@sharmainedelgado9404]

Nobody taught us in school the reasons why we study quantum mechanical models, they just straight-up discuss these topics.

[@CaliforniaGuys916]

Are these videos up to date with the new ap exam?

[@humanoporsiempre]

yup. The videos include new topics like photoelectron spectroscopy and substitutional vs. interstitial alloys. you can check by going on the 'AP Chemistry Course and Exam Description' on the CollegeBoard website. Doing some last minute studying? Me too haha; good luck!

[@sydelle3941]

Thank you Mr. Anderson. God bless.

[@sirenofamphitrite4612]

very helpful😊

[@pchemist]

I typically like Bozeman Science videos, but I'm unhappy with some of the things in this one, such as an incorrect descriptions of the HUP and spin.

[@happyperson4001]

thank you

[@macmackay2179]

Mr. Anderson, orbitals do not actually spin the way you described. Common mistake due to the label "spin"

[@yetitran8396]

wish that i could see it before being in university

[@swathiv1004]

Wonderful lecture

[@yolo-sy6zl]

Quantum of Solace mechanical model?

[@s3xyn0sfera2]

So if there can only be two electrons in an orbital where are the other electrons?

[@liamgauvreau]

in a different orbital

[@anna-ob6wb]

god bless u honestly

[@imranabdullah2326]

way better than my tutor

[@JasperKenneth06]

what was up with that intro music?? LOL! JK i love you! u help me alot! --____-- godbless u sir

[@calebstopa]

Well it's a really great video, and I understand the concept, but why would I want to know about this? Like how will I use this in my life?

[@braumh]

nice

[@ridhwaanany7480]

bozeman best vid

FYI your caps lock is stuck into the on position

[@like2upload3videos]

I must have a really good Chemistry teacher because after she explained it in class, all this stuff seems really easy to me now.. Watching this video for some revision before the test.. Chemistry's unpredictable, can never underestimate tests lel.

[@carolineocon9520]

a lifesaverrrrr

[@loissolomon9896]

Now I get it

[@nurulnadiah5218]

this may sound like a stupid question, but how to get the orientation from the shape?

[@TheStanStanmanson]

Orientation or m sub l= -l to +l
Ex:
L=2
m sub l= -2, or -1, or 0, or 1, or 2

[@InternetDarkLord]

For the 007 video, he should have had a Bond Girl.

[@sciencenerd7639]

cool

[@manishreddy3729]

it is a gud video 😘😘😄🌹

had to resort to bozeman science in an attempt to save my chemistry grade

[@uripatootie7064]

I went from being 1 of 2 who 100% last test to not knowing what the heck is going on. Do your homework everyone

[@gideonsleftnut7627]

haha, it's a double pun, it also references quatum of solace

[@latashapaddy1391]

Anyone watch Rick and Morty? lol this explains what was going on in episode 1 of season 2 >.

[@bosskid101]

This video + Me = Mind fucked

[@arixii3796]

Names Bond, JAMES BOND

[@Wishjsiwpqpq]

No

[@InSummaryYT]

no

[@Obamnaz]

I think the orientation number is missing a non-binary option. Otherwise great video!

[@Dubbelehalvezool]

Stll not fantastic but at least a much more thorough description (not an explanation) of what's really happening.

[@daytonchan6262]

i lost you at chemistry
