WebThe distance between the two protons in a molecule of H2 is 74 picometers (10 -12 meters), whereas two protons in the same nucleus are about a femtometer apart (10 -15 meters). In other words, the two protons are about 75000x further apart in a molecule of hydrogen than an atom of helium. WebAnswer (1 of 3): You can't. Helium is an element, meaning the only way to synthesize it is with nuclear reactions. Either fusion or fission. Neither is particularly cheap. If you did figure out a way to mass-produce helium in a cost-efficient manner, screw the helium, you've just revolutionized ...
