Nuclear chemistry is a branch of chemistry that focuses on the study of radioactive substances, nuclear reactions, and the behavior of atomic nuclei. It explores the properties and transformations of atomic nuclei, including processes such as radioactive decay, nuclear reactions, and the synthesis of new elements.

Nuclear chemistry deals with the structure and stability of atomic nuclei, as well as the various types of radiation emitted during nuclear reactions. It also involves the study of nuclear processes for applications such as power generation, nuclear medicine, radiocarbon dating, and materials analysis.
