      I believe that would be Hydrogen – Atomic number 1! Making anything bigger requires a huge amount of energy (like at the centre of a star), so a lot of the known universe is made up of Hydrogen! After that Helium – atomic number 2 – is the most common and then, oddly, Oxygen – atomic number 8!

      As Aimee said, hydrogen (H) is the most abundant element in the Universe followed by helium (He).
