Two small nuclei can merge into one nucleus {fusion, physics} {nuclear fusion}|. Fusion releases million times more energy per mass than burning.
products
Nuclear fusion makes all atoms up to and including iron.
efficiency
Nuclear hydrogen fusion to helium makes 0.007 of mass into energy, so efficiency is 0.007. Other fusions make 0.017 of mass into energy. If efficiency is less, universe has no or less helium and heavy atoms. If efficiency is more, universe has more helium and heavy atoms, but no hydrogen. Carbon production also depends on ratio, because it involves resonance energy.
