What is the significance of a negative Q. value in a nuclear reaction?
Correct answer: B. The reaction requires external energy
- A. The reaction is spontaneous
- B. The reaction requires external energy
- C. The reaction produces no energy
- D. The reaction violates conservation laws
Explanation
A negative Q value indicates that the mass of the products is greater than the reactants, requiring external energy input to drive the reaction, making it endothermic.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
