Share:
- 1Fluorine has the highest electronegativity because it possesses both the highest electron affinity and highest IE1 in Group 17.
- 2Electronegativity is not defined for noble gases on Pauling scale; from B to F, values increase due to increasing Zeff and decreasing atomic radius.✓
- 3Ne has the highest electronegativity in the second row because of its maximum nuclear charge.
- 4Electronegativity increases uniformly from B to Ne due to monotonically increasing nuclear charge.
Correct answer
Electronegativity is not defined for noble gases on Pauling scale; from B to F, values increase due to increasing Zeff and decreasing atomic radius.
