Question

Which of the following is an example of nuclear fission?

a) 1n + 235U → 139Ba + 94Kr + 31n
b) 90Sr → 90Y + e-
c) 226Ra → 222Rn + 4He
d) 2H + 3H → 4He + 1n

Answer 1

2H + 3H → 4He + 1n is an example of nuclear fission

Explanation :

Nuclear fission is a process in which two smaller nuclei are formed because of the splitting of a large nucleus. The process of nuclear fission occurs when a nucleus absorbs the neutron that produced because of radioactivity decay of another atom.

In the equation 2H + 3H → 4He + 1n, there is nuclear fission between Titrio and Deuterium. Helium is thrown as products with the emission of neutrons. This reaction gives an energy of about 17.6 MeV .

About 80 percentage of energy from this reaction is released in the form of neutron.

Answer 2

The correct answer is D). See the explanation below, please.

Step-by-step explanation:

Option D corresponds to the nuclear fission between Deuterium and Titrio, throwing Helium as products and with the emission of a neutron.
