Question

why can the fusion of iron into heavier elements not support a star? fusing iron into heavier elements consumes energy rather than releasing energy, resulting in the star collapsing. fusion involving iron emits too many cosmic rays, causing the core of the star to weaken and collapse. actually, it is possible for iron fusion to support a star. fusing iron into heavier elements emits too much energy and results in the star exploding as a supernova.

Explanation:

In stellar fusion, lighter - element fusion releases energy which supports the star against gravitational collapse. When iron fuses into heavier elements, it requires energy input instead of releasing it. This lack of outward - pushing energy causes the star to collapse.

Answer:

Fusing iron into heavier elements consumes energy rather than releasing energy, resulting in the star collapsing.
