How did the first chemical element appear in the universe?

Big Bang nucleosynthesis began roughly about 20 seconds after the big bang, when the universe had cooled sufficiently to allow deuterium nuclei to survive disruption by high-energy photons. (Note that the neutron–proton freeze-out time was earlier). This time is essentially independent of dark matter content, since the universe was highly radiation dominated until much later, and this do… WebLight elements are formed when high-energy particles called photons interact with electrons in a low-pressure region.

Elements are synthesized in discrete stages during the lifetime of a star, and some steps occur only in the most massive stars known ( Figure 24.6.2 ). Initially, all stars are formed by the aggregation of interstellar “dust,” which is mostly hydrogen.

Webreactions, the nuclei of most elements lighter than iron can be formed (fig. 1). Scientists call this process nucleosynthesis (for “synthe-sis of nuclei”).
