Compounds and Molecules

A chemical compound is a bound combination of atoms in the ratio of small whole numbers. Compounds are represented by molecular formuli which indicate the numerical ratios of combination.

Atoms are held together by chemical bonds. Visualizing the kinds of compounds which can form is aided by Lewis symbols and diagrams.
