9 F 18 longrightarrow x E y+ +1 e0 x=8, y=18 ∴ x E y= 8 O 18 ∵ Position has one unit of the charge and zero mass. Thus, F 18 changes to O 18 therefore resulting decay product is C 6 H 5 O 18.

Q. $C_{6} H_{5} F^{18}$ is a $F^{18}$ radio-isotope labelled organic compound. $F^{18}$ decays by positron emission. the product resulting on decay is

$C_{6} H_{5} O^{18}$

$C_{6} H_{5} A r^{18}$

$B^{12} C_{6} H_{5} F$

$C_{6} H_{5} O^{16}$

$_{9} F^{18} ⟶_{x} E^{y} +_{+ 1} e^{0}$
$x = 8, y = 18$
$∴_{x} E^{y} =_{8} O^{18}$
$∵$ Position has one unit of the charge and zero mass.
Thus, $F^{18}$ changes to $O^{18}$ therefore resulting decay product is $C_{6} H_{5} O^{18}$ .
