An ionic bond, by definition, is a bond formed by a metal and a nonmetal.

Potassium is an alkali earth metal, and oxygen is a nonmetal.

Therefore, they form an ionic bond.

Answer: ionic

Explanation: Ionic bond is formed by the complete transfer of electrons from a metal to a non metal.

In potassium hydroxide
(KOH) there is complete transfer of electrons from potassium to hydroxide.

$K^++OH^-\rightarrow KOH$

Covalent bond is formed by sharing of electrons. Metallic bond is formed in metals.
