Common mistake

Misinterpreting Fusion Diagrams

Students often confuse the arrangement of nuclei in diagrams, misidentifying the reactants and products of fusion.

Carefully analyze the diagrams, noting the labels and the number of protons and neutrons in each nucleus to accurately identify the fusion process.
