Balance the nuclear reaction, Xe 54 118 → ? + I 53 118

Let the atomic number and atomic mass for the missing entity be Z and A respectively. Balancing given nuclear reaction from conservation of charge and mass: 118 + A = 118 ⇒ A = 0 54 + Z = 53 ⇒ Z = - 1 Thus, the balanced nuclear reaction will be: Xe 54 118 → e - 1 0 + I 54 118

Write pairs of isotones and one pair of mirror nuclei from the following, B 5 10 , C 6 12 , 13 27 Al , C 6 11 , Si 14 28 .
