Look at the list below.

Question

I. The division of the nucleus into fragments.
II. The combining of atomic nuclei.
III. The kind of reaction that fuels the stars.
IV. The kind of reaction that emits additional protons.
Which among these pertain to nuclear fusion reactions?

Answer 1

Among the statements you provided, the ones that pertain to nuclear fusion reactions are:

II. The combining of atomic nuclei. III. The kind of reaction that fuels the stars.

Statement II directly defines nuclear fusion as it involves the fusion or combining of atomic nuclei to form a heavier nucleus. Statement III also pertains to nuclear fusion because it describes the process that powers stars, where hydrogen atoms fuse to form helium and other heavier elements, releasing a tremendous amount of energy in the process.

Statements I and IV do not pertain to nuclear fusion:

• I refers to nuclear fission, where the nucleus divides into fragments.
• IV describes a reaction that emits additional protons, which is typically associated with certain types of nuclear reactions, but not specifically nuclear fusion.
