    Splitting a Helium atom would require energy, not release it. Up until iron, fusion releases energy. For larger atoms, it’s fission that releases energy.

      And this is the very reason that iron (Fe) is the heaviest element that is created at the core of stars. Any heavier elements can only be created by highly energetic events like supernovas. Yay for physics!
