# Is K_2O an empirical formula?

Mar 4, 2017

Yes.........

#### Explanation:

The empirical formula is the simplest whole number ratio that defines the ratio of constituent atoms in a species. The molecular formula is always a multiple of the empirical formula, and SOMETIMES, as here, the multiple may be $1$.

Here, we have ${K}_{2} O$, an ionic species with the $\text{antfluorite}$ structure.
