Red giants produce "metals", i.e., heavier elements.
The first step is helium conversion into
carbon
Answer;
Carbon
Explanation;
In the cores of extremely hot red giants, nuclear reactions convert helium to carbon.
- A red giant star is a dying star in the last stages of stellar evolution. In the main sequence stage stars convert hydrogen into helium through nuclear fusion.
- As stars in the main sequence stage slowly converts their core from hydrogen to helium the fusion continues to create a shell and soon the Helium core begins to shrink, and visible of the star change. The star becomes a red giant.
- In the red giant core the nuclear reactions convert helium into carbon. This happens when the temperature reaches 100 million K, and the nuclear fusion of He to Carbon begins, creating carbon and releasing energy.
