Did you know?
WebFeb 1, 2024 · So, radioactive decay produces ionizing radiation. However, radioactive decay also results in other effects such as neutron emission and electron capture. Your question … WebThis can be done by firing high-speed particles into the nucleus of an atom. When struck, the nucleus may absorb the particle or become unstable and emit a particle. In either case, the number of particles in the nucleus would be altered, creating an isotope. One source of high-speed particles could be a cyclotron.
Early researchers found that an electric or magnetic field could split radioactive emissions into three types of beams. The rays were given the names alpha, beta, and gamma, in increasing order of their ability to penetrate matter. Alpha decay is observed only in heavier elements of atomic number 52 (tellurium) and greater, with the exception of beryllium-8 (which decays to two alpha particles). … WebRadioactivity.

WebApr 28, 2024 · Alpha decay is a type of radioactive decay in which a particle with two neutrons and two protons (Helium nuclei) is ejected spontaneously from the nucleus of a radioactive atom. During alpha decay, an atom’s nucleus sheds two protons and two neutrons. Alpha particles are Helium nuclei. Alpha decay occurs in very heavy elements …
