Module 2 Intro

Module 2—Chemical Compounds

Lesson Summary

In your study in this lesson you considered the following questions:

• What models are used to describe the bonding between atoms in molecular compounds?
  
  
• Can information contained within the periodic table be used to support and explain bonding theories?

In this lesson you learned about Lewis structures and formulas. Lewis formulas are commonly used to represent the bonding between atoms in molecular compounds. In the next lesson you will continue to draw Lewis formulas for compounds and further analyze important aspects of the bonding that exists within molecules.

You may wish to prepare answers to the questions listed above as a way to record what you have learned in this lesson. If you do this, place a copy of your answers in your course folder.

Lesson Glossary

double bond: an attraction between atoms in a molecule due to the sharing of two pairs of electrons in a covalent bond

structural diagram: a visual representation of a chemical compound that shows the relative placement of every atom within the compound, in addition to all intramolecular bonds
