Question

Which of the following is the main result of nuclear fission?

(a) Helium

(b) Strontium

(c) Krypton

(d) Barium

The question was asked during an interview.

Enquiry is from Nuclear Force topic in division Nucleus of Physics – Class 12

Answer 1

The correct option is (d) Barium

For explanation I would say: The breaking of a heavy nucleus into two or more fragments of comparable masses, with the release of a tremendous amount of energy is called nuclear fission. The most typical fission reaction occurs when slow-moving neutrons strike Uranium 235 to form the main product barium. The nuclear reaction is given as:

\( _{92}^{235}\)U + \(_0^1\)n ➔ \( _{56}^{141}\)Ba + \( _{36}^{92}\)Kr + 3\( _{0}^{1}\)n + 200 MeV
