Answer:
When there is an input of energy from nuclear fission reactions in the star, the elements are formed. IV. When the elements combine, they produce a nucleus with a mass greater than the sum of their masses.
Explanation:
Just as the development of cosmology relied heavily on ideas from physics, especially Einstein’s general theory of relativity, so did theories of stellar structure and evolution depend on discoveries in atomic physics. These theories also offered a fundamental basis for chemistry by showing how the elements could have been synthesized in stars.
