While Uranium-235 is commonly used in nuclear power plants, the isotope U-238 is more commonly found in nature. a) How many neutrons are in the nuclei of U-235? b) How many neutrons are in the nuclei of U-238? Given the mass of 1 proton is 1.007825 amu, 1 neutron is 1.008665 amu and the binding energy of 1 amu is 931.49 MeV(1 .MeV= 1 x 10^6 eV). c) If the mass of U-235 is 235.0439299 amu, what is the mass defect in amu? d) What is the binding energy in MeV?
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.
