Chapter 13, Problem 10STP

Interpretation Introduction

Interpretation:

The polyatomic ions need to be explained with examples.

Concept introduction:

Polyatomic ion means an ion which contains more than one atom and exists as one unit.

Answer to Problem 10STP

The ion which contains more than one atom which exists as single entity sharing the net charge is polyatomic ion.

Examples of polyatomic ions are:

$C{N}^{-1},S{O}_4{}^{-2},C{O}_3{}^{-2}$

Explanation of Solution

The word polyatomic ion it self suggests that an ion which is made up of more than one type of atoms.

Therefore

$C{N}^{-1},S{O}_4{}^{-2},C{O}_3{}^{-2}$

All are polyatomic ions.
