What is the composition of the sun? I will be grading on speed, accuracy, multiple sources (to see that you didn't just pick the first answer you saw), and length (keep it short and to the point, or no best answer for you! I don't want a half-page narrative). Thanks! :)

Wait... How would the percentage of total atoms differ from the percentage of total mass?

Sun's Photospheric compostion by Mass:
Hydrogen 73.46 %
Helium 24.85 %
Oxygen 0.77 %
Carbon 0.29 %
Iron 0.16 %
Neon 0.12 %
Nitrogen 0.09 %
Silicon 0.07 %
Magnesium 0.05 %
Sulphur 0.02 %
Element Abundance --- Abundance (percentage
(percentage of total --- of total mass)
number of atoms)
Hydrogen 91.2 --- 71.0
Helium 8.7 --- 27.1
Oxygen 0.078 --- 0.97
Carbon 0.043 --- 0.40
Nitrogen 0.0088 --- 0.096
Silicon 0.0045 --- 0.099
Magnesium 0.0038 --- 0.076
Neon 0.0035 --- 0.058
Iron 0.0030 --- 0.14
Sulfur 0.0015 --- 0.040
sorry that table is so sloppy... no good way to do it quickly.
**EDIT** To answer your question: Total atoms differs from total mass because different atoms have different atomic weights, thus different masses.

Mostly hydrogen and helium with a couple percent of various other things thrown in to allow a good set of spectral signature lines ☺
As for how the percentage of atoms and mass can be different, it's called isotope ratio. Not all atoms of the same (chemically identical) element have the same mass. Some of them have extra neutrons (or are missing a neutron of two) in their nuclei

The sun is made mostly of Hydrogen and Helium. That's were it get's it's power from - converting Hydrogen into Helium. It also has traces of heavier elements as well.

Hydrogen and helium and some of the rocks that originally made up the bulk of the solar system!
