(Or both if the description applies to both fission and fusion.) Comes together to form larger particles. Involves isotopes like hydrogen and helium. Produces energy in the center of our Sun. 1. Fission Breaks into smaller particles. 2. Fusion Follows Einstein's equation: E =mc- 3. Both Involves heavy isotopes like uranium and plutonium. Produces electrical power in nuclear power plants around the world. II 20 F7 F1 F2 F3 @ # % 3 4 5 8 2 6 Q W E R T Y U
