Question

Which one of the following statements is incorrect?
(A) Greater the nuclear charge, greater is the negative electron gain enthalpy
(B) Nitrogen has almost zero electron gain enthalpy
(C) Electron gain enthalpy decreases from fluorine to iodine in the group
(D) Chlorine has highest electron gain enthalpy​

Answer 1

Answer:

(A)

Explanation:

Electron gain enthalpy is the energy released when an electron is added to an isolated gaseous atom.

Its value is negative and the ease with which an atom accepts electrons its electron gain enthalpy becomes more negative that is, its value increases

Answer 2

Answer:

option A

Explanation:

option A is incorrect since greater the nuclear charge less is electron gain enthalpy( Electron Affinity)
