How did ernest Rutherford discover the atom?
Ernest Rutherford develop the idea that the atom has nucleus by using gold foil and alpha particles. Basically He shot the poistive laser to the gold foil which contains positive and negitive, and he saw the reflection of it and it tells us that there is positive charge to reflect positive laser with is proton. J.J Thomson already discover the electron, who has negative charge. Then Rutherford figured out the nucleus is positive.

What is a nanoscope used to do?
The nanoscope is a high tech microscope that is used to view very small objects. It's an imaging system that uses atoms instead of light in order to view tiny particles.
How does streamline help reduce air resistance?
As air particles hit against the object, it produces air resistance and therefore slowing down the spped of the object. A streamline object can avoid the air particles hitting its surfaces directly. Instead of hitting onto it and slowing it down, a streamline shape allows the particles and travel around it. Hence, reducing air resistance so it can remain its high speed. Hope this will help but don't trust it entirely After all, I am only 14
Why do quantum physicist typically use models to study atomic particles instead of observing atomic particles directly?
Atomic particles are too small to be easily observed directly.
Why did Rutherford conclude that an atoms nucleus has a posotive charge instead of a negative charge?
when carrying out the alpha scattering experiment, he observed that some alpha particles got deflected from their course. as alpha particles are helium nuclei, they are positively charged. the fact that they deviate made him think that there might be some repulsion between the particles and the nucleus. as positive charges repel each other, he determined the nucleus to be positively charged.
If Rutherford made bombarded aluminum foil with alpha particles instead of gold foil what observations would he have used?
The scattering angles would have changed, but the qualitative results would also change: the reason Rutherford chose gold was because it is EXTREMELY malleable. One can stretch gold foil until it is only a few atoms thick in places, which is not possible with aluminum. If the foil were too thick, there would be no transmission of particles at all; the whole point was to demonstrate that most alpha particles passed through unchanged, but some of them scattered, which is only possible with a VERY thin foil.
How did the Rutherford experiment prove the existence of the nucleus?
The Gold Foil experiment demonstrated the (at the time) surprising result that atoms had nuclei. The prevaling model for atoms at the time has been described as "grapes in Jell-O" (with electrons - "grapes" - suspended in a uniform field of positive charge, the "Jell-O"), and the alpha particles Rutherford (actually, it was his students, Hans Geiger and Ernest Marsden) was shooting at the foil were expected to pass nearly straight through with only minor deviations. Instead, what was observed was what Rutherford described as "firing a 15-inch shell at a piece of tissue paper and having it come back and hit you," because it turns out that all the positive charge in the atom is concentrated within a very small region ... the nucleus, and the alpha particles recoiled quite strongly from this concentration of charge.
What Rutherford discover in his gold foil experiment?
He found that the atom was made up of mostly empty space.

After 1911 most scientists accepted the theory that the nucleus of an atom was very dense and very small and has a positive charge. What led scientists to accept this theory?
The breakthrough was the alpha particle scattering experiments of Marsden, Geiger and Rutherford. Basically they fired a beam of alpha particles (which are small, positively charged particles emitted by some radioactive sources), at a thin metal foil. Unexpectedly, instead of the slight scattering of the beam they expected, they found a very few particles were scattered back towards the source. They could only explain this if the metal atoms had a tiny central nucleus with a positive charge to repel the alpha particles. If you search you should be able to find Rutherford's own account of those experiments.

What is the Contribution of ernest Rutherford to science?
Ernest Rutherford contributed to the understanding of the atom. He used J.J Thomsons model and conducted a expirements in which he shot positively charged particles throught a thin gold foil. He predicted that all the high speed particles would pass straight through the foil without being affected by the gold atoms. Instead, the results showed that while most particles did behave as predicted, some were greatly deflected.
