The gold foil is 15 microns thick, and the gold atoms atoms are in the nanometer range how many layers of gold atoms does the helium nuclei need to avoid to pass through without deflection? Thousands? Why is only one gold atom shown in the model? That doesnt look like an accurate model to me How frequently are the alpha particles being emitted? Does gold foil that thick present an effectively solid wall of gold? If helium nuclei pass through easily, how about helium atoms? How about water? Wouldnt a pin-ball sort of behavior be expected for the alpha particles? Helium is a noble gas, but a helium with a +2 charge would be an incredibly reactive ion, desperately seeking electronscould it react chemically?? These are the sorts of questions that anyone would wonder about I do

thanks for providing with such clear explanation :) this is easy to understand indeed!

I'm here because of my assignment
Comment from : Milford Vital

Maybe i sound stupid but How can there be particles of a particular charge all disposed in a container?

That's my father He was a really intelligent guy and I am still so proud of him <3brI say 'was' he passed away from cancer in 2013brBut it's nice knowing that if I want to hear his voice again all I have to do is watch this videobrThank you

Someone get the door!
Comment from : Shroom Duke

It's REALLY cool to be able to see this experiment-I've only seen it in books!brThank you so much!
Comment from : madsciclare

Thank you! I finally understand
Comment from : Marion Crandle

thank u so much
Comment from : Sini Varghese

That bell is extremely annoying and distracting After the first 2 rings, its not funny anymore
Comment from : DutchPhlogiston

preety gud one
Comment from : Paridhi Rai

I thought gold consist of millions of atoms The one shown here only has one atom (nucleus)
Comment from : Bee

My dog was barking at the door all through this Good way to link Rutherford's experiment with Cern
Comment from : Virginia Jones

So useful Its good to know that someone out there knows what he's doing :-) br
Comment from : Toasted Duck

I can't focus on what he is saying with that door bell ringing noise
Comment from : U WUT M8?

it helped me so much in my studies
Comment from : Rahul Gautam Sharma

yeahit wasn't too long agoonly a century back ;)
Comment from : almas

I put on video, walked away heard the bell ring, paused the video checked who was at the door, walked back pressed play, heard it again paused this happen one more time reset, the video read what it said! and :) lol
Comment from : Chapterlegend

the brass can? does brass behave the same way that Lead did back in Rutherfords day?
Comment from : Marvin Cervantes

So nobody knew about the atomic nucleus before his experiments? that is amazing to me! It wasn't that long time ago :X
Comment from : Eduardo lugo

it would be assumed that the experiment took place in a vacuum, to reduce the enviromental impact on the experiment
Comment from : Unikun Man

I dont normaly like dodgy top comments on a good science video But that nearly made me choke on my bong Cheers
Comment from : TheProCactus

Easier to make thin enough, even if it is expensive
Comment from : namapro

what about background radiation
Comment from : farefouse olly

Nice :D
Comment from : TheCRTman

It has nothing to do with interference Copper and aluminum are more likely to oxidize than Gold Interference is caused by inductance or magnetic fluctuations caused by alternating electrical current
Comment from : sharnrock

nice
Comment from : Himasekhar Vemuru

Exelente !
Comment from : Vernon Bellini

the ghost in the atom wants to know if you're home
Comment from : lomertamahon1

why gold ?
Comment from : Durameter21

that bell is really annoying
Comment from : Paul Salt

excellent thank you
Comment from : Wanna BeAthlete

A lot of speaker wire and headphone jacks/plugs today use gold plating/wires as well since it causes the least amount of interference You could probably get gold the same way from there as well ^^
Comment from : dmidc

A-level physics :'(
Comment from : Giuseppe Marziano

nice science!!
Comment from : Yashodeep Sant

exactly however i gave it a like as it was interesting
Comment from : ESaif

After every deflection would the nucleus of the Gold foil would it loose energy?
Comment from : xDeviLZeee

Man, I really want to do this, but I have no gold foil
Comment from : Takeru Chii

Sorry, this video is awesome, but that fucking bell ringing is awful
Comment from : Tom Murphy

Well but the electrons were not spread randomly, as what shrodinger said that the electrons are spread in organised clouds of electrons
Comment from : jack fadi

wt abot the alpha particle vch mak head to head contact with the nucleus? that part is not mentiond here any hv nyc n imformative
Comment from : TheRaybreaker

12 people obviously had a teacher assign this to be watched
Comment from : sorrydogz

Excellent explanation and experiment recreation Subscribed

the video

how can i download it
Comment from : Airaz Abu

thank you for a reconstruction of the rutherford experiment
Comment from : Rithesh R Prabhu

The door bell is very irritating

oh darn thats really annoying ^^ tipping my doorbell used to sound like the button sound from LOST

Hi millennium students :D
Comment from : thebrodyperk

am i the only one who wanted this guy to say the word "strawberry" the whole time? straw-bur-ee
Comment from : Allie Stewart

me like science
Comment from : 1AaronDanger

how this experiment can show the actual geometry of an atom?! You can only speculate about it
Comment from : ActiveStorage

shut that f**king bell up !!!!!
Comment from : 93hickey

thanks good video
Comment from : Chucktage

Great presentation (but you need to see an American dentist, right away!)
Comment from : Peter Wexler

Hey, nix that annoying bell sound !
Comment from : cell151

You just suckzz
Comment from : Youthpickup

The bell could be outside the jar I think the digital counters are outside as well
Comment from : VV Egon Spengler

this is reallly cool
Comment from : Aleena B

By far the best explanation of Rutherford's Gold Foil Experiment and Plumb Pudding model that I"VE ever seen
Comment from : fluxcapacitor05

i cant remember
Comment from : Mubashir Mateen

why the doorbell sound it almost stoped me from watching this video, learn not to use such irritating sounds the next time DX
Comment from : MrSuperZangief

Is there a vacuum in the bell jar?
Comment from : VV Egon Spengler

Would somebody get the door!?
Comment from : zbret

i hate british people but this is interesting just my opinion

I only study chemistry for the methamphetamine business
Comment from : Gary Niger

Gotta Love Chemistry
Comment from : Mike Mason

answer your damn door!
Comment from : Michael Lovegrove

@iiAngelic A negative and negative deflected like a magnet and how he found out I believe was by using a nucleus that was negatively charged so every time a electron would go thru it would bounce back in various directions
Comment from : Brendalovesjesus96

@Mrleopleasure I know I don't get the use of knowing this, except for the use of wanting to make an atomic bomb
Comment from : Brendalovesjesus96

excellent video, thanks
Comment from : NemesisX26

@iiAngelic this is wat i understand alpha particles r positive so wen they come in contact with the proton very close they deflect back i'm i correct if u get the correct answer tell me pls
Comment from : joel7308

i am so confused i hate this crap
Comment from : leo J

i still don't understand why do the particles bounce back?
Comment from : Linabella

This is the best explanation of the Rutherford Experiment I've ever watched Very clear and it has a working replica of the experiment
Comment from : purplehayabusa

nyc one
Comment from : Mohit Koli

@flakemusic86 hahahaha, it got me too I went to the door thinking there was someone!
Comment from : Simba Mwendapole

@vk2zay The range of alpha particles from Am-241 in air @STP is about 413 cm
Comment from : kyle3420

History and practicality together Great video Quit worrying about the bell, it's just a BELL!
Comment from : CoyoteBuddy

I thought one of Rutherfords students were responsible for this laborious experiment? Is this true?
Comment from : nodariel

@zapo147 thank you! :-)
Comment from : NGC3982

That Bell Is SO annoying
Comment from : Hamish

@thewindowproject The distribution of particles is proportional to 1/sin^4(O/2)
Comment from : SchumiUCD

Awesome experiment! Awful doorbell!
Comment from : matthias3895

Do they ever take quantum effects into consideration in this particular experiment?
Comment from : Ell

@vk2zay it was pumped down yes
Comment from : BackstageScience

the person who disliked thought there was someone at the door and kept pausing the video and running to the door
Comment from : LolxDBart

Awesome channel, Brady! I only found out about it today! I wish you got rid of the cheesy 80's educational video music, though :/
