Rutherford's Experiment: Nuclear Atom

Rutherford's Nuclear Atom Experiment
In 1910, Rutherford and his coworkers were studying the angles at which alpha particles were scattered as they passed through a thin gold foil. Most particles passed through undeflected, though a few were found to be scattered at large, some even in the direction they had come. This meant they had collided with an object much more massive than the particle itself, but so small that only a few aplha particles encountered them. Showing that the atom was composed of a small dense massive center surrounded by low mass electrons.

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

answer -"splitting the atom".

LOL=OWNED

Ha Ha Ha, Classic

Don't forget the LoTR films

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! =)

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

I guess it was done in 1909

[blankrofl]

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

@MrSimon565 My thoughts:

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

"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

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