Final answer:

Potassium (K) and bromine (Br) will form an ionic bond, as potassium loses an electron to become K+ and bromine gains an electron to become Br-.

Step-by-step explanation:

The type of bond that potassium (K) and bromine (Br) will form is an ionic bond. Potassium is a metal from group 1 on the periodic table, which means it has a tendency to lose an electron and form a positive ion. Bromine, on the other hand, is a nonmetal from group 17, which means it has a tendency to gain an electron and form a negative ion. When these two elements combine, potassium donates its electron to bromine, resulting in the formation of positively charged potassium ions (K+) and negatively charged bromide ions (Br-). The electrostatic attraction between these oppositely charged ions results in the formation of an ionic compound, commonly represented as KBr (potassium bromide).
