Scientists debate this subject and revise percentages when new data becomes available. We won't be around to see it, but when the universe is thousands or millions times older than it is now, helium may overtake hydrogen as the most abundant element (or not, if enough hydrogen remains out in space to far from other atoms to fuse). This chemical element with symbol S and atomic number 16 is the first in this list, and yet it is still in abundance. Much more of the galaxy consists of something else! ThoughtCo.
