The only stable nucleus of fluorine is . What type of decay is expected from ? — Nuclear Chemistry and Radioactivity Chemistry Question

💡 Solution & Explanation

$\text{F}^{18}$ has fewer neutrons than the stable $\text{F}^{19}$, making it neutron-deficient. It will undergo positron emission (or electron capture) to convert a proton into a neutron and increase its stability. Therefore, correct answer is C.
