← ScienceWhich outcome occurs when electron capture proceeds within stellar nucleosynthesis?
A)Decreased neutron-to-proton ratio results✓
B)Increased average atomic binding energy
C)Photodisintegration reaction cross-section rises
D)Plasma confinement temperature threshold lowers
💡 Explanation
Electron capture converts a proton to a neutron via weak interaction; therefore, decreasing the abundance ratio, because fewer protons exist rather than some subsequent change to binding energy parameters arising alone from temperature effects.
