Vedclass · Answer

(A) In positron emission, the atomic number of the nucleus decreases by $1$ while the mass number remains constant. The decay reaction for $F^{18}$ is: ${ }_{9}F^{18} \longrightarrow { }_{8}O^{18} + { }_{+1}e^{0}$ Since the $F^{18}$ atom is part of the $C_{6}H_{5}F^{18}$ molecule, the $F^{18}$ nucleus transforms into an $O^{18}$ nucleus. Therefore, the resulting decay product is $C_{6}H_{5}O^{18}$.

$C_{6}H_{5}F^{18}$ is an $F^{18}$ radio-isotope labelled organic compound. $F^{18}$ decays by positron emission. The product resulting from the decay is:
