Question

2,8,6 and 2,8,7 which is more electronegative ​

Answer 1

Answer:

2,8,6 near the center circle

Answer 2

Answer:

2,8,6 is the electron configuration of sulphur

and 2,8,7 is that of chlorine

Chlorine is more electronegative than sulphur because it has valency 1 only and it can get stabilized by just adding an extra electron but sulphur is the element of same period having valency 2 due to which it need two electrons to get extra stability and also the effective nuclear charge increases in case of Cl-atom...

so the 2,8,7 is more electronegative than 2,8,6
