Question 47

One radioactive isotope used in medical imaging and thyroid cancer treatment is iodine-131 (I).

Iodine-131 decays by emitting a beta particle ( $β\beta$ ) to form xenon (Xe).

Complete the following nuclear equation by writing the correct numbers in the box.

{}_{53}^{131}\text{I} \rightarrow \boxed{\phantom{{}_{00}^{00}}}\text{Xe} + {}_{-1}^{0}\beta
