A heavy nucleus of mass `M_(x)` decay into two nuclei (Y and Z) of masses `M_(y)`and `M_(z)` . The Q value of the reaction is

A radioactive nucleus A at rest disintegrates into two nuclei B and C . Mass of B is 12m and that of C is 4m .The Q -value of the reaction is Q=(h^(2))/(24m lambda^(2)) .The energy liberated in reaction is completely imparted to the products (B and C) as kinetic energy.

A radioactive nucleus X converts into nucleus Y by emitting B^+ . If atomic masses of X and Y are M_X and M_Y then Q value of reaction will be :-

The mass of nucleus ._(z)X^(A) is less than the sum of the 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 mass m_(1) and m_(2) only if (m_(1)+m_(2)) lt M . Also two light nuclei of massws m_(3) and m_(4) can undergo complete fusion and form a heavy nucleus of mass M ''only if (m_(3)+m_(4)) gt M ''.
