      I don’t actually know this for definate. But I know in the universe it’s hydrogen. On earth we have a lot of oxygen and hydrogen in water and hydrocarbons (that’s oil, coal, living matter). So I’d take an educated guess that oxygen, hydrogen, carbon and silica are probably the most abundant materials.

      if you mean the Earth, without the atmosphere, then oxygen and silicon (which form a lot of the rocks). in the atmosphere, nitrogen. in the oceans, hydrogen, which combines with oxygen to make the water. I’m not sure which wins!
