We have seen the nuclear equation for the beta decay involved in radiocarbon dating. Now complete the equations for each of the following 2 decay reactions, using ⁰ _–1β to represent the beta particle:

Strategy

We can use both the mass numbers and the charges given to determine the missing particles in the equations, much as in the previous example for alpha decay.
