What happens to a positively-charged alpha particles that comes the positively-charged nucleus?
It will repel

What happens to a nucleus of an unstable atom?
An unstable nucleus can undergo radioactive decay to become more stable. This can involve emitting radiation in the form of alpha particles, beta particles, or gamma rays. The decay process results in a transformation of the nucleus into a different element or isotope.
Rutherfords alpha scattering experiment showed that the charge on the nucleus of the atom must be?
Rutherford's alpha scattering experiment showed that the charge on the nucleus of the atom must be positive because the alpha particles were deflected by the concentrated positive charge in the nucleus.
What are the charged particles in a nucleus?
Protons, which are positively charged. The other particles that are in a nucleus are Neutrons, but Neutrons are not charged, Neutrons don't have a charge.
What did Rutherford call the region that deflected the alpha particles?
Rutherford called the region in the gold foil experiment that deflected alpha particles the "nucleus." He discovered that the positive charge and most of the mass of an atom were concentrated in this small, dense region.
How did Rutherford know the nucleus was positively charged?
Rutherford conducted the famous gold foil experiment, where he observed that some alpha particles were deflected back at large angles when they passed through thin gold foil. This led him to propose that the positive charge of an atom is concentrated in a small, dense region called the nucleus.
What happens when strong forces are not sufficient enough to hold an unstable nuclei together?
When strong forces are not strong enough to hold an unstable nucleus together, the nucleus can undergo radioactive decay. This can result in the release of particles or energy, such as alpha or beta particles, to stabilize the nucleus.
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
Type of nuclear decay consisting of a helium nucleus?
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
What do you think are the chances of alpha particle directly hitting the nucleus?
What do you think are the change of the alpha particles directly hitting the nucleus
Which particles is similar to a He nucleus?
The so-called alpha particles ARE helium nuclei.
What factors will affect the extent of scattering of the alpha particles?
The factors that will affect the extent of scattering of alpha particles include the charge and mass of the nucleus they interact with, the impact parameter (closest approach distance), and the energy of the alpha particles. Additionally, the angle of deflection will be influenced by the velocity and direction of the alpha particles as they approach the nucleus.
Why the alpha particles could not smash the nucleus apart?
The alpha particle is positively charged (as is the nucleus) and is heavy compared with the neutron that is neutral and lighter than the alpha particle.Another viewpoint:It depends what experiment the question is about. For example, over a hundred years ago, Rutherford bombarded gold foil with alpha particles and some "bounced off" what we now call the nucleus of the atoms. However, about ten years later he did experiments in which alpha particles did indeed "split" atomic nuclei. So, sometimes alpha particles can certainly smash a nucleus apart.
Alpha particles ejected from the nucleus travel at the speed of light?
Alpha particles are emitted from the nucleus at high speeds, typically around 5-10% of the speed of light. They move with such energy due to the strong repulsive force between the positively charged alpha particle and the remaining nucleus.
Why did the path of only some alpha particles deviate?
nucleus of the atom has positive charge.alpha particles are also positively charged.like charges repel each other.so alpha particles passing near the nucleus are repelled and deviated from the normal path
Does alpha particles have less mass the beta particles?
An alpha particle is two protons and two neutrons (same as a Helium nucleus) so when a nucleus ejects an alpha it will defintely have less mass. Also it will be a new element because it has two less protons.
Why was existence of a tiny massive and positively charged nucleus was deduced from the observations?
Why or how? The number of alpha particles deflected was small ... indicating the nucleus was small. The deflection of an even smaller amount of alpha particles almost straight back toward the emitting source proved that the nucleus was heavier than the alpha particle. According to previous atomic theory, the alpha particles should have all gone straight through the metal foil, with none deflected. Math calculations based on the deflection pattern showed that the nucleus was repelling the alpha particles, that they were not actually hitting and bouncing off the nucleus... this showed that the nucleus was positively charged.
What type of particles are released as part of alpha decay?
It is the alpha particle, which is actually a helium-4 nucleus, that is emitted during alpha decay. The helium-4 nucleus, you'll recall, consists of two protons and two neutrons.See the links below for more information.
