The methods explained here are approximations that don't take into account the position of the electrons and other factors. ejected from the nucleus. There are two protons in the helium nucleus and two neutrons. For instance, we could determine that 817O817O is a product of the nuclear reaction of 714N714N and 24He24He if we knew that a proton, 11H,11H, was one of the two products. I've got a test coming up soon and I cannot fail. Now as the equations are unbalanced, we will be balancing them as, Reaction Rate and Reactor Power Calculation Multiplying the reaction rate per unit volume (RR = . If it is a positron, it will not act like an electron because it has a positive charge, which will repel it from anything that an electron would interact with. What is the difference between nuclear reactions and radioactive decay processes?
