Step 1:: Recall that ions are atoms or molecules that have gained or lost electrons, resulting in a net charge.
The size of an ion is influenced by its charge and the number of electrons in its outermost energy level.
Step 2:: Compare the sizes of $\mathrm{K}^{+}$ and $\mathrm{K}$.
Potassium $\mathrm{K}$ is an alkali metal with one electron in its outermost energy level.
When it loses this electron to form $\mathrm{K}^{+}$, the remaining electrons occupy a smaller volume, making the $\mathrm{K}^{+}$ ion smaller than the neutral $\mathrm{K}$ atom.
