    In any fission process the ratio \[\frac{\text{mass}\,\text{of}\,\text{fission}\,\text{products}}{\text{mass}\,\text{of}\,\text{parent}\,\text{nucleus}}\,\] is:  [AIPMT (S) 2005]

    A)  less than 1       

    B)       greater than 1

    C)  equal to 1

    D)                   depends on the mass of parent nucleus

    Correct Answer: A

    Solution :

    In fission process, when a parent nucleus breaks into daughter products, then some mass is lost in the form of energy. Thus, mass of fission products < mass of parent nucleus
       \[\Rightarrow \] \[\frac{\text{Mass}\,\text{of}\,\text{fission}\,\text{products}}{\text{Mass}\,\text{of}\,\text{parent}\,\text{nucleus}}\text{1}\]
    Note:    1. Nuclear fission was discovered by Ottohan and Strassman.
    2. In each fission reaction a tremendous amount of energy \[(\approx \,190\,MeV)\] is released.
