Ernest Rutherford's contribution to the atomic structure due to the gold foil experiment?
Ernest did an experiment where he shot alpha particles into a gold foil that proved the concept of a nuclear atom, that is an atom with a nucleus made of protons and neutrons and have electrons moving around the nucleus in some way. His experiment did not show the position of electrons or energy levels or even how they moved.

The gold foil experiment supplanted the plum pudding theory. Thegold foil experiment led to the discovery that most of the atomsmass is located in the dense nucleus.

The correct answer should be a he told them that there can be other elements that would be in the world.
i really have no idea you know what i mean thats why i asked this site. but you dont know it and guess what? i dont either
You see...the gold foil experiment was basically when alpha particles He 2+ ions were fired into a thin sheet of gold foil..It was done by Hans Geiger and Ernest Marsden( stud…ents of Rutherford)..Now basically the model of atom then was that what is called the"plum model" or "apple pie model"..or whatever you wish to call it..the basic idea of course was that positive charge was spread around the atom with electrons embedded in them.Now,of course the spread out positive charge,could not deflect the doubly charged alpha particles by much..why?because the positive charges are all spread apart and the field they set up would gradually weaken with distance and hence the total field strength at a given point would not be large enough to deflect the particle.So,they obviously expected small deflections ,but ahat they found amazed them..some of the particles actually was reflected by more than 90 degrees and most of them passed through.."It was like firing a 15-inch long shell in a piece of tissue paper and it came back to hit you"..so now what could this mean?Rutherford concluded that since the particles reflected back,there must be a strong positive"nucleus"..and since most of the particles passed right through,most of the space in an atom must be empty..I think that's about it!!
It showed that the positive charge was concentrated in a very small area, rather than being spread out. We now call this small area the nucleus. Rutherford was a bit surprise…d when some of the particles he "fired at thee foil bounced right back. This would not have happened if the charge was disperse. By the way, he actually used platinum foil, although all the books say gold!
the existence of a dense, positively charged center in an atom
After that famous experiment, it was realized that atoms were mostly empty space.
is mostly empty space
What is a conclusion about the atom's structure gained from Rutherford's gold foil-alpha particle experiments?
The conclusion is that the positive charges in an atom are concentrated in a fairly small space, now known as the nucleus.
Rutherford's new model for the atom, based on the experimental results, had the new features of a relatively high central charge concentrated into a very small volume in compa…rison to the rest of the atom and containing the bulk of the atomic mass (the nucleus of the atom).
Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom. A short answer for the Rutherford atomic model: the atom is composed from a c…entral part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles. .
In Gold and Precious Metals
The alpha particules went straight threw the gold foil
In Gold and Precious Metals
that the atom mostly consisted of empty space.
What did Ernest Rutherford's experiment with gold foil determine about the volume and makeup of an atom?
Do Rutherford's gold foil experiment led to the discovery of the portion of the atom known as the nucleus?
shail = whale to the power of 2
1. Atoms are mostly empty space. 2. Atoms have a small, densenucleus. 3. That nucleus is positively charged.
