← ScienceWhich consequence during stellar nucleosynthesis decreases element abundance?
A)Decreased nuclear binding energy✓
B)Increased Coulomb repulsion
C)Lowered fusion cross-section
D)Elevated stellar core temperature
💡 Explanation
Reduced element abundance occurs with decreased binding energy leading to lighter, more stable nuclei, thus favouring alpha particle formation rather than heavier element creation because nuclear binding dictates stability, and temperature alone doesn't overcome this.
