Easy

One radioactive isotope used in positron emission tomography (PET) medical imaging is fluorine-18 (F).

Fluorine-18 decays by emitting a positron (β+\beta^+β+) to form oxygen (O).

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

918F→0000O++10β {}_{9}^{18}\text{F} \rightarrow \boxed{\phantom{{}_{00}^{00}}}\text{O} + {}_{+1}^{0}\beta 918​F→0000​​O++10​β
