Alpha particles interact with atomic nuclei by what is called scattering. An atomic nucleus will recoil from the scattering event somewhat, but the heavier the nucleus being "hit" by the alpha particle, the more the alpha particle will "bounce off" that nucleus. These interactions are not as "physical" as some we are familiar with, like billiard balls acting on each other, but the analogy is a good one. We actually say the alpha particle is scattered and comes away with less energy and the nucleus comes away having taken a bit from the alpha particle. With very small nuclei, the results are much more dramatic, particularly when we look at those elements with the lowest atomic numbers. As you can imagine, the smaller the atom, the more it reacts in the scattering process. A hydrogen-1 nucleus will "go flying" if it is involved in a scattering event with an alpha particle. And you can easily visualize that, too. Use the links below to related questions to learn more.
It will repel
When a positively charged alpha particle collides with a positively charged nucleus, they experience a strong repulsive force due to their like charges. This repulsion can prevent the alpha particle from penetrating the nucleus. If the energy of the alpha particle is sufficiently high, it may overcome the Coulomb barrier and interact with the nucleus, potentially leading to nuclear reactions such as fusion or scattering. However, under normal circumstances, the alpha particle will simply be deflected away from the nucleus.
When a positively-charged alpha particle directly hits a positively-charged nucleus, it experiences a strong electrostatic repulsion due to the like charges. This repulsion can cause the alpha particle to be deflected away from the nucleus, preventing it from penetrating further. If the energy of the alpha particle is high enough, it may overcome the repulsive force, resulting in nuclear reactions or the emission of radiation, but typically, it is repelled.

The name of a positively charged particle in the nucleus is proton.
This particle is the proton.
The positively charged particles in an atomic nucleus are protons.
A positively charged particle has great difficulty penetrating a target nucleus because of the strong repulsive electrostatic force between the positively charged particle and the positively charged protons in the nucleus. This repulsion acts as a barrier that prevents the particle from approaching the nucleus closely.
