Question

which equation represents a nuclear fusion reaction?
a

b

c

d

Explanation:

• Nuclear fusion is the process where two light - nuclei combine to form a heavier nucleus.
• In option C, \(_{1}^{2}H\) (deuterium) and \(_{1}^{3}H\) (tritium) are light nuclei that combine to form \(_{2}^{4}He\) (helium) and a neutron \(_{0}^{1}n\).
• Option A and B are beta - decay processes (\(_{37}^{87}Rb\) and \(_{6}^{11}C\) are undergoing radioactive decay).
• Option D is a nuclear fission process (a heavy nucleus \(_{92}^{235}U\) is splitting into lighter nuclei \(_{56}^{142}Ba\) and \(_{36}^{91}Kr\) after absorbing a neutron).

Answer:

C. \(_{1}^{2}H+_{1}^{3}H
ightarrow_{2}^{4}He + _{0}^{1}n\)
