    Hydrogen. It is the basic building block of all the elements. Fuse two atoms of hydrogen together and you have helium.

    It is possible that we will discover dark matter and that could be the most abundant. Neutrinos are also very abundant but we don't have a good estimate of them yet because they are difficult to detect. However, of what we know for certain it is pretty much in order from the start of periodic chart up. Hydrogen, then Helium makes up not only most of the Sun but most of the planetary mass in the solar system. This makes up most of Jupitor, Saturn, Uranus, and Neptune. Hydrogen will fuse into Helium and Neon and Lithium and the other elements up to Iron. Fusion stops releasing energy at iron. To get anything heavier than iron you need a supernova where heavier elements are created because of the massive concentration of extra energy and as the star explodes these are scattered into space.
