Question

During spontaneous radioactive decay,

• A. atomic number must increase
• B. binding energy of product must be higher than binding energy of reactant
• C. mass number must change
• D. ratio of neutron & protons must increase

Answer 1

The correct option is B binding energy of product must be higher than binding energy of reactant

In a spontaneous reaction, energy is released. This means binding energy is more for the products, and they are more stable than the reactants.
