Question

question 5 what is the heaviest element created by fusion inside of stars & why? iron - fusion with iron requires more energy than it creates uranium - it is radioactive, so when a star makes it, the star switches to fission for power neon - it is the heaviest gaseous element a star can create before exploding as a type la supernova krypton - its the final element left from a dying planet

Explanation:

In stars, nuclear fusion is the energy - producing process. Fusion reactions release energy until iron is formed. When attempting to fuse iron nuclei, more energy is required than is released, which halts the fusion process in the star's core. Uranium is not created by normal stellar fusion, neon is lighter than iron and krypton is not relevant to the end - stage of stellar fusion in this context.

Answer:

iron - fusion with iron requires more energy than it creates
