What are the most abundant elements in the universe?

Hydrogen, then Helium, ect

Since it is the simplest element—consisting of one proton and one electron in the S-orbital—hydrogen is the most abundant element.

The next simplest element is helium, which is composed of two electrons, one proton, and one neutron. For more information, see this Wikipedia page.
