ACTIVITY: Infographic — Chemical Abundances: The Sun
The Sun is composed primarily of hydrogen and helium, with a smattering of other elements that account for less than 2% of its mass. Download a PDF of Chemical Abundances: The Sun infographic.

- Shouldn't something as hot and as large as the sun have a wider chemical diversity? Or is it too hot?
The chemicals are there but they are in very meager amounts.(2 votes)
- In the universe, Hydrogen is dominant... so stars are primarily composed of Hydrogen when they start out. The term used to describe the other elements they contain is called metallicity. The higher their metallicity, the more the star contains of other elements.(5 votes)
