Which type of stars have elements that have higher atomic masses?
Answer:
Stars that have elements with higher atomic masses are known as massive stars. Massive stars, also called high-mass stars, are stars that have initial masses higher than about 8 times the mass of our Sun. These massive stars have the capability to generate heavier elements through nuclear fusion processes in their cores.
During the lifecycle of massive stars, they undergo a series of fusion reactions that result in the creation of elements with higher atomic masses. The fusion process starts with the conversion of hydrogen into helium and then progresses to fuse helium into heavier elements like carbon, oxygen, nitrogen, and eventually elements as heavy as iron.
The most massive stars, towards the end of their lives, can undergo supernova explosions, during which extremely high temperatures and pressures allow for the formation of even heavier elements, including those with the highest atomic masses. These elements are then dispersed into the universe, enriching the surrounding space with heavy elements that can be incorporated into the formation of new stars and planets.
