Hydrogen. The Sun is made up of about 75% hydrogen and 25% helium. About 0.1% is metals (made from hydrogen via nuclear fusion). This ratio is changing over time (very slowly), as the nuclear reactions continue, converting smaller atoms into more massive ones.

On the surface it's been stated. Inside who knows?
You need to ask a geometry question on the ratio of surface to volume. You may be surprised at the ratio.
