Web22 sep. 2009 · Nuclei are positively charged and thus repel each other. The kinetic energy of the nuclei must be very large for nuclei to be able to fuse, such as at the surface of the sun, where hydrogen... Web3 jun. 2024 · Stars consist mainly of hydrogen, which is used for the fusion reactions that produce almost all of their energy. In this process four hydrogen nuclei fuse to form a helium nucleus. However, this does not happen directly, and actually happens in stages: Two protons fuse to form a deuterium nucleus, and releases a neutrino and a positron.
WebCarbon could be formed by the fusion of three alpha particles, but the probability is relatively so low that this would be too slow to explain the observed carbon abundance. … WebIt takes three helium 4 nuclei to fuse to make one carbon 12 nucleus. Its called the triple-alpha process, because helium 4 nuclei with two protons and two neutrons were …
