Unformatted text preview: is: a + A ® B + b · In all nuclear reactions, the sum of atomic numbers and mass numbers on both side of the equation must be equal. For example: 56 26 2 1 Fe + 28039 Bi ¾¾ 109 M t + 1 n ® 26 6 0 H + 98 M o ¾¾ 99 T c + 1 n ® 43 42 0 · Large amount of energy is released in nuclear reactions and as a result a significant 2 amount of mass is converted to energy. Einstein’s equation, E = mc , can be used to calculate the amount of energy released in a nuclear reaction. Example: 1. Calculate the mass loss and the amount of energy released in the nuclear reaction shown below: 7 3 Li + 1H ¾¾ 4 He + ® 1 2 7.016 g 1 .0 08 g 4.003 g Mass of reactant = Mass of products = Mass Loss = 2 Energy released E = mc = 8 4 2 H e + energy 4.003 g Chemistry 52 Chapter 18 MASS DEFECT · The mass of the nucleus is actually less than the sum o f the masses of the protons an...
