WebAfter hydrogen, helium is the most abundant element. Most of it was probably produced in the initial big bang. Furthermore, as described earlier, helium is the normal ash of hydrogen consumption, and in the dense cores of highly evolved stars, helium itself is consumed to form, successively, carbon-12, oxygen-16, neon-20, and magnesium-24. WebIn the case of the Sun, the major ele-ment produced is helium. The conditions at which the natural repulsive forces of positive nuclei can be overcome and forced to join together are tremendous. Here are a few facts about the Sun to show the conditions that bring about the nuclear fusion or “burning” of hydrogen to helium. The Sun has a radius
