Answer:
Helium
Explanation:
A star usually begins at small hydrogen gas that is formed through gravitational force and collects several dense spheres. When the star created reaches a specific size, it is ignited by the nuclear fusion process and generates enormous energy.
The fusion process compressed the hydrogen atoms together, transforming large elements. After the disappearance of the star for many years, it releases heavier elements such as gold. Therefore helium is formed through a natural radioactive process of elements such as thorium and uranium.
