Full Answer

An atom of potassium loses an electron to form a positive ion, while the chlorine atom gains an electron to form a negative ion. The electrostatic force of attraction between the positive potassium ion and the negative chloride ion leads to the formation of an ionic bond. This allows the formation of a molecule of potassium chloride. Potassium chloride has a three-dimensional lattice structure in its crystals, which is similar to common salt sodium chloride. Potassium chloride dissolves in water and has a melting point of 1,418 degrees Fahrenheit.
