Chapter 8, Problem 147AP

Interpretation Introduction

Interpretation:

Resonance structures for ${\text{H}}_3^{+}$ are to be drawn and $\Delta H^{\circ }$ is to be calculated.

Concept introduction:

The octet rule states that every element in the main group should have eight electrons in its valence shell in order to attain a noble gas configuration.

Valence electrons are those electrons that occupy the last shell of an element.

Lewis dot symbols contain dots, which give information about valence electrons.

Lewis structures show bonds as lines and lone pairs as dots.
