Experimental A hydrogen (Ht) or helium (He+) ion beam extracted from 4 MV Van de Web1 dag geleden · Expert Answer. The sun generates its energy through nuclear fusion, making helium from hydrogen. The main process by which this happens, called the proton-proton chain, goes as follows: - Two protons come together to create deuterium, a positron, a neutrino, and energy: p+p → D +e+ +v+ energy - The deuterium fuses with another …
