Nuclear Chemistry  

 

  • Nuclear chemistry is the one of the  branches of chemistry that deals with the study of the nucleus in an atom.

 

  • A nuclear reaction is different from a chemical reaction.In a chemical reaction, atoms of the reactants combine by a rearrangement of extranuclear electrons but the nuclei of the atoms remain unchanged. an atom which is involved.

 

  • The number of protons or neutrons in the nucleus changes to form a new element. A study of the nuclear changes in atoms is termed Nuclear Chemistry.

 

  • The initial progress in this branch was done by Pierre Curie and Marie Curie by isolating natural radioactive elements and investigating their properties.

 

  • The phenomenon of spontaneously and continuously emitting active radiation is called radioactivity and the substance emitting such radiation is called radioactive.

 

  • The spontaneous breaking down of the unstable atoms is termed radioactive disintegration of radioactive decay. A nuclear reaction is one which proceeds with a change in the composition of the nucleus so as to produce an atom of a new element.

 

  • The nuclear reaction is represented by an equation indicating the nuclear characteristics of the reactants and the products as The conversion of one element to another by a nuclear change is called transmutation.
