Diagram of an oxygen atom When a star has changed all of its hydrogen atoms into helium, it turns into a red giant and moves on to convert the helium atoms into [...]
Diagram of a nitrogen atom Inside a red giant star, the star smashes lighter atoms together. Smashing atoms gets the star energy to burn, and also leaves extra heavier atoms. Nitrogen [...]
Diagram of an iron atom When a red giant star finishes changing all of its helium into carbon and oxygen, it then starts to turn the carbon and oxygen atoms into iron atoms. Iron [...]
