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.
So that the experiment can be remembered,repeated or useful the point of doing an experiment is to collect data.
So the experiment's results are more reliable
Inquiries
The control remains the same in an experiment so that you have something to compare the outcome to.
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.
No, Ernest Rutherford's student James Chadwick wondered where all of this extra mass came from so in a experiment he discovered the neutrons.

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.
Rutherford supervised the experiment in his famous beta particle scatter experiment with gold foil, so he is given credit.
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.
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.
because he freaked his girl and she freaked and sucked the rest of the world so it got affect
Ernest Rutherford, the renowned physicist and father of nuclear physics, was raised in a religious household with strong Presbyterian beliefs. However, as he delved deeper into scientific research, his views shifted towards agnosticism. Rutherford's scientific discoveries and empirical evidence led him to prioritize rationality and skepticism over religious dogma.
Discovery of the proton happened so slowly and by so many that it is impossible to give just one scientist credit for it. Physicists Rutherford, who is credited with discovering the nucleus, is also credited with coining the name proton.
Neutrons were discovered through experiments involving bombarding beryllium with alpha particles. Neutrons were not created in these experiments, but were instead found as subatomic particles that make up the nucleus of atoms.
,Rutherford alpha scattering experiment proved that most of the particles passed through the gold foil undeflected it means most of the volume occupied by atom is empty and few particles deflected it means there is centre of positive charged called nucleus,so hence proved whole mass of an atom is located in the centre..
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.
