Webtogether to produce Helium. It looks like this in a very simplified way: H + H He + ENERGY. This energy can be calculated by the famous Einstein equation, E = mc2. Each of the colliding hydrogen atoms is a different isotope of hydrogen, one deuterium and one tritium. The difference in these isotopes is simply one neutron. WebHelium is the smallest and the lightest noble gas and one of the most unreactive elements, so it was commonly considered that helium compounds cannot exist at all, or at least under normal conditions.
