Chapter 4.9, Problem 8QQ

Interpretation Introduction

Interpretation:

Among given options, the chemical formula for the compound tin(II) oxide has to be chosen.

Concept Introduction:

An ionic compound has two elements one is metal and another one is non-metal.  The metal ion always has positive charge and the non-metal ion always has negative ion called binary compounds.

Example: ${\text{NaCl, CO}}_{\text{2}}$.  Here $\text{NaCl}$ is ionic and carbon dioxide is binary compound.

The following rule can be used for the naming of binary ionic compounds.

The full name of the metallic element is given first, followed by a separate word containing the stem of the metallic element name and the suffix –ide.

Depending upon the chemical circumstances metal atoms are able to form more than one type of ion and is called variable charge metal.

Example – Fe forms ${\text{Fe}}^{\text{2+}}$ and ${\text{Fe}}^{\text{3+}}$ ion.
