Work Step by Step
We are given potassium (K) and fluorine (F) and asked what type of bond is likely to occur between them. Potassium is a metal and fluorine is a nonmetal. When metals and nonmetals bond, the nonmetal attracts the electron(s) from the metal so strongly that it essentially strips the electron(s) away. This occurs because nonmetals are much more electronegative than metals, meaning they strongly attract electrons. When a bond is formed in which an electron is stripped from one atom, the bond is called an ionic bond. Metals and nonmetals form compounds through ionic bonds.
