how is fusion different from a simple chemical reaction?

Question

A. atoms come together in a chemical reaction, but they are split in a fusion reaction
B. energy is released in a fusion reaction, but it is absorbed in a chemical reaction
C. the atoms are bound to each other by electrons in a fusion reaction
D. the nuclei combine in a fusion reaction

Answer 1

D. the nuclei combine in a fusion reaction

Fusion involves the combination of atomic nuclei to form a heavier nucleus, releasing a large amount of energy in the process. In contrast, a chemical reaction involves the rearrangement of electrons in atoms to form new chemical substances, with typically lower levels of energy involved.
