Yes, they form an ionic bond.
Potassium and fluorine will form an ionic bond
The bond between the metal potassium (K) and the nonmetal fluorine (F) is ionic. During the formation of the ionic compound potassium fluoride (KF), the potassium atom loses an electron and becomes a positively charged ion, and the fluorine atom gains the electron and becomes a negatively charged ion. The electrostatic attraction between the two oppositely charged ions is the ionic bond. In general, a metal and a nonmetal will form an ionic bond.
I remember that by thinking of table salt. Basic Na(Sodium) and Cl(Chlorine) one is a metal the other is a non-metal. They have an ionic bond; same as potassium and fluorine. I remember the difference between ionic and covalent by this someones answer which said "the names bond. Ionic bond, taken not shared" Its silly but it works :)
ionic bonds
Many elements can form an ionic bond with fluorine. Metals in groups one and two (such as alkali metals lithium, sodium, potassium, etc. or alkali earth metals like magnesium or calcium) like to form ionic compounds with fluorine. This is because fluorine has an extra electron it wants to give away, and metals in group one and two want another electron to become stable.

The alkali metal potassium and the halogenfluorine will form an ionic bond.
All of the metallic elements will form an ionic bond with fluorine.

because potassium is the total opposite of ionic bond
Oh yes, potassium and chlorine form an ionic bond.
ionic bonds
Ionic bond, as the difference in electronegativity between calcium and fluorine is over 1.7
