The neutrons started decaying rapidly, and determined the "initial ratio" of H (hidrogen) and He (helium) . Without major changes to the Big Bang theory itself, BBN will result in mass abundances of about 75% of hydrogen-1, about 25% helium-4, about 0.01% of deuterium and helium-3, trace amounts (on the order of 1010) of lithium, and negligible heavier elements. Light elements Due to . Answer (1 of 6): In its "earliest"* moments, there were no elements in the universe, only pure energy.

primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to 20 minutes after the big bang, [2] and is calculated to be responsible for the formation of most of the universe's helium as the isotope helium-4 (4he), along with small amounts of the hydrogen isotope deuterium (2h or d), In physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang.

The following stages occur during the first few minutes of the Universe: Less than 1 second after the Big Bang, the reactions shown at right maintain the neutron:proton ratio in thermal equilibrium. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. natklee27 natklee27 Answer: A. Big bang nucleosynthesis was the creation of elements heavier than hydrogen, mainly helium. Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. Light elements B. Answer: Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. Explanation: Big Bang nucleosynthesis, abbreviated as BBN, also known as primordial nucleosynthesis took place after the Big Bang for about 10 s to 20 minutes and resulted in the yield of isotopes of helium-4 (), helium-3 which accounts for most of the world's helium, other . About 1 second after the Big Bang, the temperature is slightly less than the neutron-proton mass difference, these weak . In physical cosmology, Big Bang nucleosynthesis (abbreviated BBN, also known as primordial nucleosynthesis) is the production of nuclei other than those of the lightest isotope of hydrogen ( hydrogen-1, 1 H, having a single proton as a nucleus) during the early phases of the Universe. The theory of nucleosynthesis during the first few minutes after the big bang makes very clear predictions about the abundances of light atomic nuclei in the early universe - about the contributions of hydrogen (single protons), deuterium, helium-3, helium-4, lithium-7 to the total mass of ordinary matter contained within a given region. . Following Big Bang nucleosynthesis, local concentrations of gas collapsed to form the first galaxies and the nebulae and stars that comprise them.Gravity binds these immense structures together, and it is the gravitational collapse when stars form that creates the pressures needed to initiate thermonuclear fusion reactions, which convert four 1 H nuclei to one 4 He nucleus and release energy. Answer: Nucleosynthesis is the process that creates new atomic nuclei from pre-existing nucleons (protons and neutrons) and nuclei. The earliest epoch in the hot Universe which has been tested observationally is the Big Bang Nucleosynthesis epoch (BBN).

As we will see, it begins at temperature of about 1MeV and lasts until the temperature drops to a few dozen keV.

Answer: The fusion of nuclei occurred between roughly 10 seconds to 20 minutes after the Big Bang; this corresponds to the temperature range when the universe was cool enough for deuterium to survive, but hot and dense enough for fusion reactions to occur at a significant rate. the big bang nucleosynthesis refers to the production of nuclei other than those of the lightest isotope of hydrogen (hydrogen-1, 1H, having a single proton as a nucleus) during the early phases of the Universe. According to current theories, the first nuclei were formed a few minutes after the Big Bang, through nuclear reactions in a process called Big Bang nucleosynthesis. This is consistent with the standard or "big bang" model.The process of forming the hydrogen and helium and other trace constituents is often called "big bang nucleosynthesis".Schramm's figures for relative abundances indicate that helium is about 25% by mass and hydrogen about 73% with .

Primordial nucleosynthesis is believed by most cosmologists to have taken place in the interval from roughly 10 seconds to . During this epoch, known as Primordial or Big-Bang Nucleosynthesis (BBN), the primordial abundances of light elements were produced: mostly 4 He but also smaller quantities of less stable nuclei such as D, 3 He and 7 Li. The important point is that the prediction depends critically on the density of baryons (ie neutrons and protons) at the time of nucleosynthesis. A.
