WebbAn important example of nuclear fusion in nature is the production of energy in the Sun. In 1938, Hans Bethe proposed that the Sun produces energy when hydrogen nuclei ( 1 H) fuse into stable helium nuclei ( 4 He) in the Sun’s core ( Figure 10.22 ). This process, called the proton-proton chain, is summarized by three reactions: 1 1 H + 1 1 H ... how to remove harmony web protection
