Rutherford expected the alpha particles to shoot right through the gold foil. At the time it was assumed that an
atom was a mix of electrons and protons. When Rutherford shot the particles through the gold foil some of the
particles reflected back, while most just shot right through. This indicated there was a small dense positively
charged nucleus in the atom.

What is the purpose of collecting data an experiment?
So that the experiment can be remembered,repeated or useful the point of doing an experiment is to collect data.
Why are multiple trials important when carrying out an experiment?
So the experiment's results are more reliable
During an experiment which factors must be controlled so that researchers can draw a logical conclusion from the experiment?
Inquiries
What stays the same throughout an experiment?
The control remains the same in an experiment so that you have something to compare the outcome to.
What is a hypothesis and what role does a hypothesis play in a scientific experiment?
a proposal intended to explain certain facts or observations the hypothesis helps create the experiment. you have to know what you want as an outcome so you can modify the experiment so it all works out.
When neutron were discovered were these neutrons created in the experiment?
No, Ernest Rutherford's student James Chadwick wondered where all of this extra mass came from so in a experiment he discovered the neutrons.

Which scientist was the first to conclude through experimentation that atoms have positive charges in their nuclei?
Hans Geiger and Ernest Marsden. Rutherford was the supervisor and explained the unexpected results, so his name is usually attached to the experiment as well, but it was Geiger and Marsden who actually did it.
Who used polonium and gold foil in his famous experiment?
Rutherford supervised the experiment in his famous beta particle scatter experiment with gold foil, so he is given credit.
How would you describe the gold-foil experiment?
Geiger and Marsden, under Rutherford's direction, fired alpha particles at a very thin sheet of gold foil. They used a movable fluorescent screen to determine where the alpha particles went after passing through the foil. The screen emitted tiny flashes of light whenever an alpha particle struck it, so Rutherford and his team could see how the particles were being affected by the atoms they struck. Based on Thomson's model of the atom as a diffuse sphere of intermeshed positive and negative charge, Rutherford expected all of the alpha particles to pass through the gold foil with little or no scattering; indeed, they found that most of the particles passed straight through the foil, as if it weren't even there. In other words, the greatest number of flashes occurred when the screen was held directly behind the gold foil, in the path of the alpha particles. A tiny fraction of the particles, however, were reflected back toward the alpha emitter. From this Rutherford concluded that gold atoms must be mostly empty space, with tiny, dense, positively charged nuclei surrounded by extremely rarefied clouds of negative charge.
What was Dalton's gold foil experiment?
First of all it wasn't Dalton's it was Rutherford's, so google it with the right name in front and you'll probabaly get the answer.
How has Ernest Rutherford influenced society today?
because he freaked his girl and she freaked and sucked the rest of the world so it got affect
When was nucleus discover?
The nucleus was discovered by Ernest Rutherford in 1914 with his famous gold foil experiment. From the results of shooting alpha particles (radiation) at a sheet of gold foil he determined that the atom must be made of mostly empty space with a dense, positively charged center called the nucleus. This was the official discovery, though really Robert brown originally discovered the nucleus of a cell.
Name a sentence that has surprised in it?
The following sentence has surprised in it: She was so surprised that I remembered that daises were her favorite flower.
What did the particles in Rutherford' s experiment do?
Rutherford was expecting the result to be what JJ Thomson had predicted. That the Alpha Particles just pass through the gold foil, not rebound, like the result. JJ Thomson thought of this result because of his plum pudding model.
What is an evacuated chamber?
It is a chamber that consits of no particles and its inside, therefore, is a vaccum. (Get it? Evacuated > Vaccum).The volume inside of an evacuated chamber is zero and is used so an experiment conducted inside of it has little risk of being effected by particles. So in Rutherford's experiment, they use it so no gas particles/atoms/nuclei can get in the way of the alpha radiation which gets absorbed by the air after 5cm of travel and has such a large size and mass so the experiment has big chance of being affected by air particles.Hope this helps :),x BBC Merlin Fan
