In fact we can use $\text{moles}$ to measure all of these species.

#### Explanation:

The answer they probably wanted you to give was to exclude $\text{electrons}$. Nevertheless, we can certainly measure electrons using molar quantities.

For redox reactions, we could write:

$N a \left(s\right) \rightarrow N {a}^{+} + {e}^{-}$

And if a $23 \cdot g$ mass of sodium metal is oxidized, certainly $\text{Avogadro's number of electrons}$ are evolved.

$\text{Avogadro's number}$ is simply a number, admittedly it is a very large number, $6.022 \times {10}^{23} \cdot m o {l}^{-} 1$.
