Nuclear Chemistry is an aspect of chemistry that deal with nuclei of atoms. Radioactivity This is the spontaneous emission of radiation by radioactive element such as Thorium, Uranium etc. Characteristics of Nuclear Chemistry Spontaneously and continually emitting of radiation by radioactive element Temperature and pressure have no effect on radioactivity The radiation can pass through […]
Introduction Radioactivity was discovered by Henri Becquerel in 1869. In 1898, Marie and Pierre Curie succeeded in chemically isolating two radioactive elements, Polonium (z=84) and Radium (z= 88). Radioactivity or radioactive decay is the spontaneous disintegration of unstable nuclides to form stable ones with the emission of radiation. Unstable nuclides continue to disintegrate until a […]
Meaning of Radioactivity Radioactivity is the spontaneous disintegration or breaking down of the nucleus of an atom which makes it give out or emit radiation. Any element that disintegrates spontaneously and release rays us called a radioactive element Discovery of Radioactivity Radioactivity was discovered by a French physicist called Henri Becquerel in 1896. He […]
