Answer: The given statement is false.
Explanation:
When two small atomic nuclei combine together to result in the formation of a large nuclei along with emission of energy is known as nuclear fusion.
For example, [tex]^{2}_{1}H + ^{2}_{1}H \rightarrow ^{4}_{2}He + ^{1}_{0}n + 14.1 MeV[/tex]
Whereas in a nuclear fission a large nuclei splits into two or more small nuclei along with emission of energy.
For example, [tex]^{235}_{92}U + ^{1}_{0}n \rightarrow ^{90}_{36}Kr + ^{143}_{56}Ba + 3^{1}_{0}n[/tex]
Thus, we can conclude that the statement splitting apart of atomic nuclei is known as fusion, is false.
