Final answer:
Potassium (K) would bond with Chlorine (Cl) to form a molecule through ionic bonding.
Step-by-step explanation:
Potassium (K) is a metal and it typically forms ionic bonds with nonmetals. Among the options listed, the atom that potassium (K) would bond with to form a molecule is a) 1 Chlorine (Cl). When potassium (K) reacts with chlorine (Cl), the potassium atom donates one electron to the chlorine atom, resulting in the formation of an ionic bond, and the compound formed is potassium chloride (KCl).
