Question

Chlorine z 17 is more electronegative than sulphur (z= 16 ) why

Answer 1

because the valency of chlorine is 1 and the valency of sulphur is 2 so chlorine gets stable first

Answer 2

Explanation:

Along the period electronegetivity increases

electronegetivity is the ability to attract elecrons

since chlorine needs only one electron to complete it's orbit it's electron gain enthalpy is negative I.e chlorine requires less energy to gain electrons
