The reaction is balanced because the total number of protons and neutrons on both sides is equal. On the left side, 219 has 86 protons and 133 neutrons (219 - 86 = 133), and on the right side, 215 has 84 protons and 131 neutrons (215 - 84 = 131) plus the 2 protons and 2 neutrons from the alpha particle (42He), resulting in 86 protons and 133 neutrons on the right side as well.
