gold foil. He unexpectedly with then current models of atomic In 1910 Rutherford performed a classic experiment in which he directed a beam of alpha particles at a thin observed a few of the particles scattered almost directly backward. This result was not consistent structure and led Rutherford to propose the existence of a very dense concentration atomic nucleus. The alpha particle has a charge of +2e and the gold nucleus of positive charge a charge at the center of an atom-the of +79e. Suppose that an alpha particle is initially is headed directly at a gold nucleus. How close will and the alpha particle MeV (3.97 x 10° eV), and a great distance from the gold, has a kinetic energy of 3.97 the particle come to the center of the nucleus? Treat the nucleus as
Radioactive decay
The emission of energy to produce ionizing radiation is known as radioactive decay. Alpha, beta particles, and gamma rays are examples of ionizing radiation that could be released. Radioactive decay happens in radionuclides, which are imbalanced atoms. This periodic table's elements come in a variety of shapes and sizes. Several of these kinds are stable like nitrogen-14, hydrogen-2, and potassium-40, whereas others are not like uranium-238. In nature, one of the most stable phases of an element is usually the most prevalent. Every element, meanwhile, has an unstable state. Unstable variants are radioactive and release ionizing radiation. Certain elements, including uranium, have no stable forms and are constantly radioactive. Radionuclides are elements that release ionizing radiation.
Artificial Radioactivity
The radioactivity can be simply referred to as particle emission from nuclei due to the nuclear instability. There are different types of radiation such as alpha, beta and gamma radiation. Along with these there are different types of decay as well.
