Question

Quizplus · Accepted Answer

The most probable origin of elements beyond H and He in the periodic table in our Sun and solar system is from fusion reactions in the centers of earlier stars. The process of fusion combines lighter elements to produce heavier ones, and this occurs in the cores of stars. When stars die, they explode in supernovae, which can eject the newly synthesized elements into space. These ejected elements can then be incorporated into later generations of stars and planets.
