The mass defect (ΔM) for a nucleus of mass number (A), atomic number (Z) and mass (M) is given by |
$ΔM = [Z m_p + (Z - A) m_n] - M$ $ΔM = [Z m_p + (A - Z) m_n] + M$ $ΔM = [Z m_p + (A - Z) m_e] - M$ $AM = [Z m_p + (A - Z) m_n] - M$ |
$AM = [Z m_p + (A - Z) m_n] - M$ |
The correct answer is Option (4) → $AM = [Z m_p + (A - Z) m_n] - M$ |
