The six most common elements in our galaxy are as follows:
- Hydrogen: 74%
- Helium: 24%
- Oxygen: 1.04%
- Carbon: 0.42%
- Neon: 0.13%
- Iron: 0.11%
These values, obtained by spectroscopy, will give accurate estimates for local regions of the universe.
The abundance of elements in more distant galaxies will have lower percentages of heavy elements (ie heavier than Helium) as they have had a shorter period of time to accumulate heavy elements from stellar nucleosynthesis.

What elements by percentage do the majority of stars contain?
The percentages vary quite a lot from one star to another. The general tendency, however, is that the majority of stars contain a large percentage of hydrogen. In general, hydrogen is the most abundant element in the Universe - for now. In the future, it will gradually be used up, and there will be less hydrogen, and more of the heavier elements.
