Solution: How many atoms does each of the following prefixes specify?penta-

Solution: How many atoms does each of the following prefixes specify?penta-

Problem

How many atoms does each of the following prefixes specify?

penta-

Solution

We’re being asked how many atoms does the prefix penta- specify.


Recall that we use these prefixes in naming covalent compounds. 

A covalent or molecular compound is composed of more than one nonmetal together.

Rules for naming molecular compounds:

1. The first nonmetal is named normally and uses numerical prefixes except mono.
2. The second nonmetal keeps its base name but has its ending changed to -ide.
