Description:

Nuclear chemistry is a fascinating branch of chemistry that focuses on the study of the nucleus of the atom and the changes it undergoes. Unlike traditional chemistry, which deals with the interactions of electrons and the formation of chemical bonds, nuclear chemistry explores processes that involve the core of the atom—the protons and neutrons. These processes can result in the transformation of one element into another and often release vast amounts of energy. The story of nuclear chemistry begins with the discovery of radioactivity in the late 19th century. Henri Becquerel first observed the spontaneous emission of radiation from uranium salts in 1896, a groundbreaking finding that paved the way for further research. Marie and Pierre Curie expanded on this discovery by isolating radioactive elements like polonium and radium, laying the foundation for the field. These early pioneers helped demonstrate that atoms were not indivisible as once believed, but could undergo changes that release energetic particles. At the heart of nuclear chemistry is the structure of the atom. Each atom consists of a nucleus, made up of positively charged protons and neutral neutrons, surrounded by a cloud of negatively charged electrons. The nucleus is incredibly dense and contains nearly all of the atom’s mass. Nuclear reactions involve changes to this nucleus, either by altering the number of protons or neutrons or by splitting or combining entire nuclei. These changes distinguish nuclear reactions from ordinary chemical reactions and often involve much more energy. Duration - 1h 56m. Author - Doris Grants. Narrator - Terra Hansen.
