For a nuclear reaction $A + b \rightarrow C + d$, where $m_A, m_b, m_C, m_d$ refer to the rest masse

Question

For a nuclear reaction $A + b \rightarrow C + d$, where $m_A, m_b, m_C, m_d$ refer to the rest masses of the respective nuclei, the Q-value is defined as:

Professor PC Thomas Classes · Answer

The Q-value represents the energy released or absorbed and is determined by the initial mass minus the final mass: $Q = [m_A + m_b - m_C - m_d]c^2$.
