True
Explanation
An alpha particle is a type of ionizing radiation that can interact with atoms. When an alpha particle collides with an atom, it can transfer some of its energy to one of the atom's electrons. If the transferred energy is sufficient, it can overcome the binding energy that holds the electron in place. As a result, the electron can be ejected from the atom. When an atom loses an electron, it becomes a positively charged ion because it has more protons, which are positively charged, than electrons, which are negatively charged. This process is known as ionization. Therefore, if an alpha particle transfers enough energy to an atom, it can indeed cause the atom to eject an electron and become a positively charged ion.
