Webreactions, the nuclei of most elements lighter than iron can be formed (fig. 1). Scientists call this process nucleosynthesis (for “synthe-sis of nuclei”). In stars, these fusion reactions cannot form elements heavier than iron. up until the formation of iron nuclei, these reactions release energy, keeping the star alive. but WebHeavy elements can be formed from light ones by nuclear fusion reactions; these are nuclear reactions in which atomic nuclei merge together. The simplest reactions involve hydrogen, whose nucleus consists only of a single proton, but other fusion reactions, involving mergers of heavier nuclei, are also possible.
