Yes, chlorine is more electronegative than sulfur.

Here's why:

* Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond.

* Chlorine has a higher electronegativity value than sulfur on the Pauling scale (3.16 for chlorine vs 2.58 for sulfur).

* This means that chlorine has a stronger pull on electrons in a bond compared to sulfur.

Therefore, chlorine is more electronegative than sulfur.
