Chapter 1, Problem 9PP

Interpretation Introduction

Interpretation:

The Lewis structure for the phosphate ion $\left({\text{PO}}_4{}^{3-}\right)$ is to be drawn.

Concept introduction:

The Lewis structure of a molecule is therepresentation of the molecule in which the valence electrons of the atomsare shown.

The number of valence electrons of an atom is equal to the group number to which it belongs. Bonding atoms attaina stable electronic configuration and a stable atom generally has eight electrons in itsvalence shell.

To attain a stable configuration, atoms share their electrons with each other,
