Question

In any fission process the ratio $\frac{\text{ mass of fission products }}{\text{ mass of parent nucleus }}$ is

• A. equal to 1
• B. greater than 1
• C. less than 1
• D. depends on the mass of the parent nucleus.

Answer 1

Answer: (C)

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
$\frac{\text{ Mass of fission products }}{\text{ Mass of parent nucleus }}<1$
Note: 1. Nuclear fission was discovered by Ottohan and Strassman.
2. In each fission reaction a tremendous amount of energy $(\approx 190MeV)$ is realised
