Which of the following is a measure of the firmness or strength with which an extra electron is bound to the free atom?

A

First ionization enthalpy

B

Second ionization enthalpy

C

Third ionization enthalpy

D

Zeroth ionization enthalpy

Text Solution

Verified by Experts

The correct Answer is:
D
Zeroth ionization enthalpy is the energy required to remove an electron from an isolated gaseous anion to form free atom.
`X^(-)(g) rarr X(g) +e^(-)`
It is numerically equal to first electron gain enthalpy.
