Rutherford's Experiment: Nuclear Atom

[arjunchauhan24]

I guess it was done in 1909

[blankrofl]

Silly mrs.thomas, why did you have to put a youtube url in the chemistry packet :/

[Mber7560]

@MrSimon565 My thoughts:

"Okay, here's what you do..."

#3 weeks ago

"Oh. Damn."

[MrPendragon126]

it also shows that the nucleus was mostly made up of a positive charge and that the nucleus is mostly empty space

[heypeople702]

What is the circle thing around it made of?

[Suwaid99]

It saved me from learning huge points from my science textbook.

[kbotpop]

Mr. Lee's class anyone? lol

[little123456788]

Sick shit bro.

[applewitheveryone]

you guys saved me the effort of having to read my book...

[MaxwellHebbourn]

@applewitheveryone better to read it anyways. I got mine on my ipod :)

[houndoom1234]

I want gold foil ):

[xXmon636Xx]

I hate this shit

[Skrithuurz]

Based on Thompson model, Rutherford was expecting the alpha particles to pass through the foil without being deflected. Shouldn't he instead expect them *not* to pass through the foil?

[chemlink1]

I would like permission to show tis video in my science classes. It fits well with the course materials. I appreciate your consideration.

[wallacerolim]

fuck me 

[vuonggiabao]

what is advantages and disadvantages of this experiment?



[Philip1997SWE]

This is shit

[HetviVakharia]

very cool we have this in studies

[asianboymiggy]

thanks a lot my physics teacher expected to do an exam on this without teaching it to us

[zhadyranur]

amazing

[zhadyranur]

amazing

[starcities12]

Do they go undeflected when the gold foil is removed?

[vTheBlueprinTv]

@starcities12 well duh

[starcities12]

@vTheBlueprinTv Thank you for replying...

[vTheBlueprinTv]

@starcities12 lol no problem

[navyab1]

an usefil video

[vLes777]

OMG this video actually made me understand all of this. Text book and teacher explanations suck! We should've just been shown this!

[medoalking5]

very smart experiment , which they can know the % of the collisions by counting the glows because when A-particles hit ZnS it glows at the site of collision

[smertk]

ok but the question is:

how can the alpha particles pass through the gold foil since you can block them with a sheet of paper?

[JonnyRigby29]

@smertk because the extremely thin gold foil is only a few atoms thick whereas paper is 100 of atoms thick

[bco5678]

Okay, I'm in an honors chemistry class and I didn't understand the books explanation, or my teachers. I totally get it after watching this 47 second clip. Thanks!

[JASwarty]

@bco5678 same here

[MarieKatie242]

It was my assignment to watch this!!! Done! xD

[AlanaTheBoom]

awww, exuse me! we kiwis new zealanders ain't known for some ATOM!

we're knowen for or RUGBY!

go ALL BLACKS

[giovanemello]

Can i translate your video and insert in my page?

I put your credits in video.

Giovane

[theQandAtor]

This is the worst video I have ever seen. Both my ears and eyes are bleeding and I think I threw up on my shoe.

[lovem1231ify]

it is 9;5 and i;m sittin in the computer lab. doing this dumb thing /

thankks mr hines.

[darkgreensoldier666]

Genious

[abhinayan27]

the vid didnt show the helium particles return back ....

[mikebe41]

what is the size ratio of the particle, to the nucleus. if it is smaller, or bigger?

[TheFretTrain]

@mikebe41 The particle is definitely bigger, but the nucleus is very dense and small!

[chb3555]

i watched it mr goodland!  boring

[skyispurple]

This video is approved by the vice president of your sac!

[rbkv69]

MR CAMACHOOOOOOOO.... this. is. AWESOME.

[021hazel]

Mr Hill i watched this video...

[proteasfanz]

gold thin foil are used because gold is more malleable and ductile

[somsomone]

Why do you use gold thin foil?

[GSWarriors9]

Because its softer and more stable

[ob1benji1]

This is why I barely passed Science at OCCC

[Guevaristas]

lol Rutherford, walked past the arts centre in town today. Even they have a pic of Rutherford

[Guevaristas]

once a north american sarcastically (of course) asked me: what's  new zealand famous for?

answer -"splitting the atom".

LOL=OWNED

[HerrPingui]

Ha Ha Ha, Classic

Don't forget the LoTR films

[Lewieee]

whats the guys name that injested alpha particles and died? i think he's a russian guy?

[koskowa]

I'm studying this for chemistry

it's so easy

i have finals coming up

wish me luck =D

[ray93950]

too fast

[radicalzmovez]

how come nobody is explaining this?? i dont understand what's happening!!!!

[Fahdk2]

the flying dots are the Alpha particles( + charged) that are being emitted, the green wall is the detecting screen, it detects were the particles are hitting, the yellow window in the middle is a gold foil, as you see, 1/8000 alpha particles are repelled backwards, that's because the nucleus is VERY small, that only few on the alpha particles hit it completely and repel back.

Then Rutherford knew that the nucleus is super duper small! =)

[meghashree1]

@Fahdk2 the green wall is zinc sulphide screen which is flouroscent and glows wen alpha particles hit it

[arjunchauhan24]

@Fahdk2 Dude, 1 out of 12000 was repelled back not 1 out of 8000

[Lewieee]

the particles are positively charged and so is the nucleus, so when the particles go too close to the nucleus they get "pushed" away.

[rahulm92]

Great now this should definitely help in my project :)

[lcemt]

Great graphics and great video! An explanation would be good for someone who does not understand what was going on in this very important experiment.
