Chapter 2, Problem 23PE

Interpretation Introduction

Interpretation:

The name of the compound, ${\text{I}}_2{\text{O}}_5$ is to be determined.

Concept Introduction:

The substances that cannot be further degraded into simpler substances are known as elements.

Molecular compounds contain two or more elements of a non-metal.

First step in naming the compound is to identify the type of compound. If it is molecular compound, the first word in the name is just the first element name with an appropriate prefix to indicate the number and second word will contain the second element name with an appropriate prefix to indicate the number.

For naming of ionic compounds, the name of the metal (cation) written first, followed by the name of non-metal (anion) with suffix $-ide$, adding at the end of the anion, that is in case of monatomic ions. The hydroxide ion and cynide ion are the exceptions.
