Once you figure out stars are not a gas. nearly everything you thought was true in astronomy and nuclear physics is wrong.

Actually, if I am not mistaken, non-neutron, non-black-hole stars are generally made up of the fourth form of matter: Plasma.

[Tellurian]

The sun is almost all Hydrogen and Helium, and not much else. Those are gasses on earth, but liquids at the surface of the sun. However, they’re under gravitational pressure that’s nearly 30 times that of Earth. In the center of the sun the temperature is off the charts, causing the H & He to deform to plasma.

Depending on a star’s size and life stage, the plasma recombines to any of the scores of elements found on earth:
