Question

Which one of the following is incorrect?
a.
An element which has high electronegativity
always has high electron gain enthalpy.
b. Electron gain enthalpy is the property of an
isolated atom.
Electronegativity is the property of a bonded
atom. .
d. Both electronegativity and electron gain
enthalpy are usually directly related to
nuclear charge and inversely related to
atomic size.​

Answer 1

Answer:

a.An element  has high electronegativity

always has high electron gain enthalpy.

Explanation:

for example  the electron affinity of fluorine is lower than the electron affinity of chlorine . But fluorine is more electronegative than chlorine.
