The release of energy with the fusion of light elements is due to the interplay of two opposing forces: the , a manifestation of the , which holds protons and neutrons tightly together in the ; and the , which causes positively in the nucleus to repel each other. Lighter nuclei (nuclei smaller than iron and nickel) are sufficiently.
