Question

Joining of light nuclei of elements to form a heavy nucleus with the release of energy is called :

• A. nuclear fission
• B. nuclear fusion
• C. nuclear combustion
• D. nuclear combination

Answer 1

The correct option is B nuclear fusion

Answer is B.
In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the matter of the fusing nuclei is converted to photons (energy).
