Question 46

Easy

Fluorine-18 is a widely used radiopharmaceutical tracer in positron emission tomography (PET) imaging. It decays via positron ( $β+\beta^+$ ) emission, during which a proton inside the nucleus decays according to the equation:

{}^1_1\text{p} \longrightarrow {}^1_0\text{n} + {}^0_{+1}\text{e} + \nu_{\text{e}}

Deduce which nucleus is formed when a fluorine-18 nucleus undergoes this decay.

Use the list of proton (atomic) numbers to help you:

Nitrogen (N): proton number = 7
Oxygen (O): proton number = 8
Fluorine (F): proton number = 9
Neon (Ne): proton number = 10
