Which outcome occurs when an isotope's neutron fraction increases?

💡 Explanation

An increased neutron fraction in an actinide isotope leads to increased probability of spontaneous nuclear fission because this alters the energetics of the nucleus via increased Coulomb repulsion. Therefore, spontaneous fission becomes more likely, rather than other decay modes like alpha emission.

• Which prevents spontaneous emission from excited atomic orbitals?
• Which risk increases when a thorium-232 rod intended for use in a molten salt reactor accumulates an excess of protactinium-233?
• Which outcome occurs when a quantum dot's size decreases below a certain critical limit?
• Which outcome arises when product concentration inhibits enzymatic activity?
• Which mechanism inhibits complete oxidation if electron-withdrawing groups block enzyme active sites?
• Which consequence results when electrons fail to achieve resonance?
