If a particle hits a gold nucleus in a head-on collision, the two would come to a rest for a very brief moment and then the particle would bounce straight back. This is describing a hypothetical situation proposed for Rutherford's gold foil experiment where he confirmed a small positively charged nucleus was present in atoms.

Which particle was discovered during the gold foil experiment?
The nucleus
What is a radioactive particle that is made up of two neutrons and two protons?
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
What is the smallest particle of the element gold that can still be classified as gold?
The smallest particle in gold should in fact be gold. Gold is an element, Au, and thus should only contain gold atoms. You could also argue that some subatomic particle is the smallest particle in gold.
How did Rutherford know the nucleus was positively charged?
the nucleus is positively charged because it bounces right off of the gold foil
The smaller possible particle of gold that can exist is called?
An atom.
If an particle hits a gold nucleus in a head on collision the particle will not be deflected very much?
False, the particle will be deflected immensely.
What is the force of repulsion between an alpha particle and a gold nucleus when the alpha particle passes by the nucleus at a distance of 1pm?
superman
Which particle was discovered during the gold foil experiment?
The nucleus
What was the small positively charge particle which Rutherford directed at thin gold foil?
nucleus
Are gold atoms similar to alpha particles?
An alpha particle is the nucleus of a Helium-4 atom; therefore, it has 2 neutrons and 2 protons. A gold atom has... well, much more protons and neutrons, you can look it up if you like. Also, a gold atom normally does have electrons, whereas an alpha particle is just the nucleus (i.e., no electrons). You decide for yourself how "similar" those two are.
What is a radioactive particle that is made up of two neutrons and two protons?
Used by Rutherford in his experiment made of two protons and two neutrons are alpha particles. Rutherford discovered the nucleus using his gold foil experiment.
The kind of particle Rutherford used to shoot through gold foil?
Rutherford shot high-energy alpha particles (two protons and two neutrons, or a helium nucleus) at the gold foil. A small fraction of these alpha particles bounced back, and that is how Rutherford discovered the nucleus.
What is the smallest particle of the element gold that can still be classified as gold?
The smallest particle in gold should in fact be gold. Gold is an element, Au, and thus should only contain gold atoms. You could also argue that some subatomic particle is the smallest particle in gold.
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.
What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
What Led to the discovery of the nucleus?
Alpha particle ie doubly ionized helium atom scattering by the gold foil experiment formed the basis for the discovery of nucleus. The experiment was done by Marsden and Geiger but the experimental observation was commented and final conclusion derived by Rutherford.
What is the smallist particle of gold?
a molecule
