WebAnswer (1 of 5): It depends if you are talking about the diatomic form of hydrogen or just hydrogen atoms. Hydrogen gas is diatomic and has a molar mass of 2.0 grams while the inert helium has only one atom which has an atomic molar mass of 4.0 grams, so this would make helium 2x heavier than hyd... WebAfter hydrogen, helium is the second most abundant element in the universe. It is present in all stars. It was, and is still being, formed from alpha-particle decay of radioactive elements in the Earth. Some of the helium formed escapes into the atmosphere, which contains about 5 parts per million by volume. hemispheres voyages events sportsWebThe issue lays in what Fusion is. Atoms are generally neutral in charge. However they are not REALLY neutral. All elements have some charge to them. This isnt really a problem for basically anything. However it starts to become one if you try to smash two atoms together. Because both have the same polarity and as such repulse each other. hemisphere summer
