← ScienceWhich outcome results when core iron nuclide binding energy peaks?
A)Star collapses into type Ia supernova
B)Fusion reactions cannot yield energy✓
C)Neutron star undergoes rapid accretion
D)Hydrogen fusion proceeds unconstrained
💡 Explanation
Fusion beyond iron absorbs energy because iron is the most stable nucleus; therefore, reactions cannot yield energy due to decreased binding energy; rather than more fusion, heavier element synthesis consumes energy within the star.
