<reasoning>

Identify mass number and atomic number

\[

$$\begin{aligned} &\text{Isotope: } {}^{16}\text{O} \\ &\text{Mass Number } (A) = 16 \\ &\text{Atomic Number of Oxygen } (Z) = 8 \end{aligned}$$

\]

Calculate the number of neutrons

\[

$$\begin{aligned} &\text{Number of Neutrons } (N) = A - Z \\ &N = 16 - 8 = 8 \end{aligned}$$

\]
