D) Fusion reactions with hydrogen nuclei

Question

Quizplus · Accepted Answer

The observed pattern of abundances for elements with atomic numbers between 6 and 20 can be explained by fusion reactions with helium nuclei. These lighter elements were created in the fusion reactions that occurred during the formation of stars, and the fusion of helium nuclei is necessary to create heavier elements like carbon, oxygen, and neon. This process is called helium burning and it results in the production of many of the elements in this region of the periodic table.
