Understand this objective

Short explanation

Within Nuclear fusion (physics only), this learning objective asks you to (physics only) describe fusion of hydrogen nuclei as a process that can form helium. Focus on the approved ideas hydrogen, helium, physics only and connect them clearly to Nuclear fission and fusion. A strong response should state the relevant particle, radiation, isotope, decay, half-life or nuclear-equation idea, then explain how it answers the exact command word. Avoid swapping nearby concepts such as atomic number and mass number, isotope and ion, alpha, beta and gamma radiation, or contamination and irradiation. This is a Physics-only point, so keep the answer tied to the AQA Physics specification.

Confusing Fusion with Fission: Remember that nuclear fusion is the joining of two light nuclei to form a heavier nucleus, while nuclear fission is the splitting of a large unstable nucleus.
