WebBy the time the universe was three minutes old the process had basically stopped and the relative abundances of the elements was fixed at ratios that didn't change for a very long time: 75% hydrogen, 25% helium, with trace amounts of deuterium (hydrogen-2), helium-3, and lithium-7. Big Bang nucleosynthesis produced no elements heavier than lithium. WebJan 1, 2016 · All methods to produce more helium are so ridiculously costly that they are not worth discussing: 1) hydrogen fusion 2) bombarding other atoms (such as lithium or boron) with energetic protons in...

Webwould the failures of alchemy been seen in an attempt to synthesize helium? Disregarding alchemy, helium can be synthesized through the nuclear fusion of hydrogen isotopes. Commercialized fusion plants are at least 30 years away, assuming all the tests work. It's reasonable to assume that the helium can be captured and used in lieu of our short ... In the perspective of quantum mechanics, helium is the second simplest atom to model, following the hydrogen atom. Helium is composed of two electrons in atomic orbitals surrounding a nucleus containing two protons and (usually) two neutrons. As in Newtonian mechanics, no system that consists of more than two particles can be solved with an exact analytical mathematical approach (see 3-body problem) and helium is no exception. Thus, numerical mathematical meth… official site for optimum
