No, potassium chloride is not a non-polar molecule. It is an ionic compound composed of positively charged potassium ions (K+) and negatively charged chloride ions (Cl-). The attraction between the oppositely charged ions forms a strong ionic bond, resulting in a polar molecule.

In a non-polar molecule, the electrons are evenly distributed around the molecule, creating a neutral charge. However, in potassium chloride, the electrons are pulled towards the chlorine atoms due to their higher electronegativity, resulting in a partial positive charge on the potassium ions and a partial negative charge on the chloride ions. Therefore, potassium chloride is considered a polar molecule.
