Explanation:

Step1: Recall elementary - charge value

The elementary charge $e = 1.6\times10^{-19}\text{ C}$.

Step2: Calculate relative charge

The relative charge $n$ of an ion is given by $n=\frac{Q}{e}$, where $Q$ is the charge of the ion. Substitute $Q = 6.4\times 10^{-19}\text{ C}$ and $e = 1.6\times10^{-19}\text{ C}$ into the formula: $n=\frac{6.4\times 10^{-19}}{1.6\times10^{-19}}$.
$n = 4$. Since the charge given is negative, the relative charge is $4-$.

Answer:
