Question

Chlorine atomic no. 17 is more electronegative than sulphur atomic no. 16. Explain?

Answer 1

Chlorine has more number of valence electrons because of which it's atomic size is too far and it's need more electronegativity to pull the electron in valence shell ...

Answer 2

Answer:

Chlorine is in group 17 and Sulphur is in group 16 of the periodic table according to their electronic configurations and non metallic character increases across a period. Since Sulphur is placed before chlorine therefore chlorine is more electronegative.
