Question

1. Write the reaction equations for β ^- decays for the following nuclides.

a) lead-211

b) manganese-56

2. Write the reaction equations for β ⁺ degradations for the following nuclides.

a) phosphorus-29

b) iron-52

Answer 1

1a)

$$^{211}_{82}\text{Pb}→^{211}_{83}\text{Bi}+\beta^-.$$

1b)

$$^{56}_{25}\text{Mn}→^{56}_{26}\text{Fe}+\beta^-.$$

2a)

$$^{29}_{15}\text{P}→^{29}_{14}\text{Si}+\beta^+.$$

2b)

$$^{52}_{26}\text{Fe}→^{52}_{25}\text{Mn}+\beta^+.$$
