The chlorine atom in a molecule of hydrogen chloride (HCl) does not have a partial negative charge. In fact, it has a partial positive charge. This is due to the difference in electronegativity between chlorine and hydrogen.

Chlorine is more electronegative than hydrogen, which means it has a greater attraction for electrons. As a result, the chlorine atom pulls the shared electron pair in the HCl molecule closer to itself, creating a polar bond. This results in a partial negative charge on the hydrogen atom and a partial positive charge on the chlorine atom.
