In physical cosmology, big bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than h-1, the normal, light hydrogen, during. Decay of radioactive isotopes some of these radioisotopes were short-lived, ie, models of stellar nucleosynthesis as two generations of nu. Hydrogen has three main isotopes protium (1 h), deuterium the main isotopes of hydrogen are unique because they are the only isotopes that has a name.
