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.
If a particle hits a gold nucleus in a head-on collision, it can undergo nuclear reactions such as scattering or fusion. The outcome depends on the kinetic energy of the particle and the characteristics of the nucleus. The collision can result in the dispersal of particles, changes in atomic number, or the creation of new particles through nuclear reactions.

Which particle was discovered during the gold foil experiment?
The discovery of the atomic nucleus was made during the gold foil experiment by Ernest Rutherford in 1909. He observed that most of the alpha particles passed straight through the gold foil, indicating that atoms have a small, dense nucleus at their center.
What kind of particle is present in one gold bar?
A gold bar is made up of gold particles known as atoms. Gold is a metal with the chemical symbol Au and each gold atom contains 79 protons in its nucleus.
What is the smallest particle of the element gold that can still be classified as gold?
The smallest particle of the element gold that can still be classified as gold is an atom of gold. Gold atoms retain the unique chemical properties of gold, such as its dense, shiny, and malleable characteristics.
What is a radioactive particle that is made up of two neutrons and two protons?
A radioactive particle that is made up of two neutrons and two protons is called an alpha particle. It is a type of ionizing radiation commonly emitted by radioactive materials.
The smaller possible particle of gold that can exist is called?
The smallest possible particle of gold that can exist is called a gold atom. Gold atoms are the basic units that make up gold and can exist on their own or be part of larger structures.
If an particle hits a gold nucleus in a head on collision the particle will not be deflected very much?
Correct, due to the massive size of the gold nucleus compared to the size of the incoming particle, the particle will not experience a large deflection in a head-on collision. This is because of the concentrated positive charge in a small space in the gold nucleus that causes a very strong Coulomb repulsion when the incoming particle gets close to it.
What was the small positively charge particle which Rutherford directed at thin gold foil?
nucleus
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?
The force of repulsion between the alpha particle and the gold nucleus can be calculated using Coulomb's law, given by F = k * (q1 * q2) / r^2, where k is the Coulomb constant, q1 and q2 are the charges of the particles, and r is the distance between them. Given the charges of an alpha particle and a gold nucleus, and the distance of 1pm, the force of repulsion can be calculated to be extremely large due to the proximity of the particles and the high charges involved.

Are gold atoms similar to alpha particles?
Gold atoms and alpha particles are not the same. Gold atoms consist of protons, neutrons, and electrons making up an element, while an alpha particle is a specific type of particle consisting of two protons and two neutrons, essentially a helium nucleus. Both have different properties and behaviors.
What kind of particle is present in one gold bar?
A gold bar is made up of gold particles known as atoms. Gold is a metal with the chemical symbol Au and each gold atom contains 79 protons in its nucleus.
What subatomic particle did the gold foil experiment discover?
The gold foil experiment discovered the existence of the atomic nucleus, which is dense and positively charged. This led to the conclusion that the nucleus contains protons and neutrons, and that atoms are mostly empty space with electrons orbiting the nucleus.
What is the smallest particle of the element gold that can still be classified as gold?
The smallest particle of the element gold that can still be classified as gold is an atom of gold. Gold atoms retain the unique chemical properties of gold, such as its dense, shiny, and malleable characteristics.
Why does an alpha particle change direction when it hits gold foil?
An alpha particle changes direction when it hits gold foil because of the repulsion between the positively charged alpha particle and the positively charged nucleus of the gold atoms. As the alpha particle gets close to a nucleus, the electrostatic repulsion causes it to change direction or scatter. This experiment led to the discovery of the nucleus and revolutionized our understanding of atomic structure.
What is a radioactive particle that is made up of two neutrons and two protons?
A radioactive particle that is made up of two neutrons and two protons is called an alpha particle. It is a type of ionizing radiation commonly emitted by radioactive materials.
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
