Paragraph for Questions 15 and 16

The mass of a nucleus ZA X is less than the sum of masses of (A-Z) number of neutrons and Z number of protons in the nucleus. The energy equivalent to the corresponding mass difference is known as the binding energy of the nucleus. A heavy nucleus of mass M can break into two light nuclei of masses m1 and m2 only if (m1+m2) < M. Also two light nuclei of masses m3 and m4 can undergo complete fusion and form a heavy nucleus of mass M only if (m3 + m4) > M. The masses of some neutral atoms are given in the table below :
