Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. During the beginning of the twentieth century, many radioactive substances were discovered, the properties of radiation were investigated and quantified, and a solid understanding of radiation and nuclear decay was developed. The spontaneous change of an unstable nuclide into another is radioactive decay. The unstable nuclide is called the parent nuclide ; the nuclide that results from the decay is known as the daughter nuclide. The daughter nuclide may be stable, or it may decay itself.
Radioactive Decay – Chemistry
Uranium is a common radioactive isotope of Uranium. It is not a fissile substance thus cannot sustain nuclear fission. However this isotope is a fertile material, which means other fissile materials are generated from it. Almost all Uranium in nature is found in the form of Uranium Other isotopes like Uranium , Uranium and Uranium are found in smaller quantities in natural Uranium. Picture 1 — Uranium Source — unitednuclear. The unstable atomic nucleus of Uranium emits ionizing particles and loses energy in order to achieve a stable state.

Dana S. Uranium U is a metallic, silver-gray element that is a member of the actinide series. It is the principle fuel for nuclear reactors, but it also used in the manufacture of nuclear weapons. Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure.
