Chapter 4, Problem 4.122QP

Interpretation Introduction

Interpretation: The electron affinity for sodium ion should be determined.

Concept Introduction:

• Electron Affinity: The ability of the atom to accept the electron is called electron affinity.
• First ionization energy:

The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.

• ${\text{atom}}_{\left(\text{g}\right)}\to {\text{ion with positive charge}}_{\left(\text{g}\right)}\text{ + electron}$
• Cation: Removal of electron from the atom results to form positively charged ion called cation.
• The net charge present in the element denotes the presence or absence of electrons in the element.

To determine: The electron affinity for the sodium ion.
