The electronic configuration of the outer most shell of the most electronegative element is
Group 17 or VIIA is called the most electronegative group because of their small atomic radius due to which high nuclear attraction from the relatively more no. of protons than the no. of orbits/shells.
All the Group 17 elements have outermost ns2 np5 configuration.
The electronic configuration represents:
2s22p5= fluorine = most electronegative element
3s23p5 = chlorine
4s24p5 = bromine
5s25p5 = iodine
Thus, option (i) is correct.
