Final answer:
The structure of KCl is a giant lattice held together by electrostatic forces between oppositely charged ions acting in all directions, characteristic of an ionic bond.
Step-by-step explanation:
The correct statement that best describes the bonding and structure of KCl is c) A giant lattice structure held together by electrostatic forces between oppositely charged ions and we act in all directions. KCl forms an ionic bond because of the large difference in electronegativity between potassium (K) and chlorine (Cl) atoms. The loss of an electron from potassium and the gain of that electron by chlorine create K+ and Cl- ions, which are held together by the electrostatic force of attraction.
The ions are arranged in a three-dimensional crystal lattice structure, optimizing the attractive forces between opposite charges and minimizing repulsion between like charges. This structure is not a simple molecule but a continuous array of ions extending in all directions, resulting in high melting and boiling points and the ability to conduct electricity when in solution.
