Chapter 5, Problem 75QRT

(a)

Interpretation Introduction

Interpretation:

The elements that are $\text{+2}$ ions paramagnetic in the first transition series has to be identified.

Concept Introduction:

Diamagnetic:  When atoms or ions with all electrons are paired their magnetic field effectively cancels each other.  Substances with paired electrons are called diamagnetic.  They are weakly repelled by magnetic fields.

Paramagnetic:  Atoms or ions with unpaired electrons are attracted to magnetic field.  Substances with unpaired electrons are called paramagnetic.

(b)

Interpretation Introduction

Interpretation:

The elements with $\text{+2}$ ions and chloride ion show paramagnetism has to be identified.
