How light elements are formed
WebElements, planet Earth and us. “We are literally the ashes of long dead stars.”. Scientists believe that the Solar System was formed when a cloud of gas and dust in space, made up of elements formed deep within stars, started to collapse, forming a solar nebula.

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
WebThe former case is more familiar from chemistry class, since a lot of the common light elements used in biology (like oxygen, carbon, and nitrogen) have the same number of protons as neutrons. But it turns out that the case of carbon having 6 protons and 8 neutrons, while not as stable as 6 and 6, is stable enough that it can actually occur in … Web6 dec. 1999 · Richard Brill.

WebThe formula is B = ( Zmp + Nmn − M) c2, where mp and mn are the proton and neutron masses and c is the speed of light. It has been determined experimentally that the binding energy per nucleon is a maximum of about 1.4 10 −12 joule at an atomic mass number of approximately 60—that is, approximately the atomic mass number of iron.
