Chapter 8, Problem 141DIA

(a)

Interpretation Introduction

To Explain: The reason behind the general trend of increasing ionization energy on moving left to right across the period.

(b)

Interpretation Introduction

To Explain: An unusual decrease in first ionization from $\text{Mg}$ to $\text{Al}$ and an increase in electron affinity from Mg to Al.

(c)

Interpretation Introduction

To Explain The first ionization energy of $\text{S}$ is slightly less than that of $\text{P}$.

(d)

Interpretation Introduction

To identify: The correct hypothesis.

(e)

Interpretation Introduction

To Write: The formula for a compound and identify the hypothesis it follows.
