Chapter 14, Problem 14.133P

Interpretation Introduction

Interpretation:

Among the given oxygen ions, ions that are paramagnetic have to be identified.

Concept Introduction:

Paramagnetic:

• Paramagnetic substance contains unpaired spin of electrons that is $\uparrow \text{or}\downarrow$  and are attracted by magnet.  Example: oxygen and fluorine.
• The electronic configuration of oxygen shows two unpaired electrons and fluorine shows single unpaired electron.

Diamagnetic:

• Diamagnetic substance contains paired spin of electrons that is $\uparrow \downarrow \text{or}\uparrow \downarrow$  and are repelled by magnet.  Example: Neon and argon.
• The electronic configuration of neon shows no unpaired electron.
