Solution: The first ionization energy and the electron affinity of Ar are both positive values.What is the significance of the positive value in each case?

Problem

The first ionization energy and the electron affinity of Ar are both positive values.

What is the significance of the positive value in each case?

Solution

We are asked to determine the significance of having positive ionization energy and a positive electron affinity for Ar.

Let us define ionization energy and electron affinity.

  • Ionization energy
    • the amount of energy required to remove an electron from the gaseous form of that atom or ion
    • always positive for a neutral atom
