It is Hydrogen, with one protron and no neutrons.
There are two isotopes of hydrogen, deuterium and tritium, which exist in much lower percentages. Tritium is radioactive and decays.
The second most common element is helium. Both hydrogen and helium were created before the stars formed. Helium is also the waste produce of the fusion of hydrogen by a star.
All the other elements up to iron are created during the normal life of a star, which is often billions of years. The elements beyond iron are created during the explosive stage of a nova or supernova, typically in a few seconds. Thus any atom above helium here on earth was created by a star that no longer exists.

On earth the most abundant element is Hydrogen. I don't know about the rest of the universe.

HI FRIEND! ITS HYDROGEN.AS THE MAJOR ELEMENT OF SUN,JUPITER,THE BIRTH OF THE STARS,IN EARTH WATER IS MAJOR PART AND IT CONTAINS 2/3 HYDROGEN.
Hydrogen is the most abundant element in the known Universe; helium is second. However, after this, the rank of abundance does not continue to correspond to the atomic number; oxygen has abundance rank 3.LESS THAN 10% OF UNIVERSE HAD BEEN DISCOVED AND ACCORDING TO THAT THING ONLY WE HAVE THIS INFORMATION.!.

Its Hydrogen...
It is there in all the stars.. Their energy is derived from the fusion of hydrogen atoms...
It is present in water..
Being the lightest element, with just one proton and one electron, it was the first element to form when matter started forming from plasma... At one point, there was only hydrogen all over the universe.. over time, they fused to form heavier elements..

Should be Hydrogen or Helium. Most stars are fuelled by Hydrogen and spent fuel manifests as Helium.

Definately Hydrogen, two thirds of the world is covered by H2O, it definately beats anything else hands down.

Hydrogen...Most of the stars are made of hydrogen

+1 on Hydrogen.
Is it a coincidence that it's Number 1 the periodic table of the elements? I dunno, but it's the lightest element too.
