WebThe reactions that could form the lightest elements beyond hydrogen and helium are shown in Figure 16.8. The formation of beryllium is speculative, as we do not have evidence that it was actually produced by BBN. What's more, any that was produced could well have been destroyed inside stars since then. WebWhere Your Elements Came From. The hydrogen in your body, present in every molecule of water, came from the Big Bang. There are no other appreciable sources of hydrogen in the universe. The carbon in your body was made by nuclear fusion in the interior of stars, as was the oxygen. Much of the iron in your body was made during supernovas of ...
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. Webthe links between the chemical elements has brought—and keeps bringing—many sur-prises and interesting discoveries.
