Final answer:
Stellar nucleosynthesis creates elements such as carbon, nitrogen, oxygen, calcium, and iron.
Step-by-step explanation:
Stellar nucleosynthesis creates several elements. In stars with masses higher than about 8 solar masses, nuclear reactions involving carbon, oxygen, and still heavier elements can build up nuclei as heavy as iron. This process of creating new chemical elements is called nucleosynthesis. The elements created through stellar nucleosynthesis include carbon, nitrogen, oxygen, calcium, and iron.
