Atoms bond chemically to form molecules.

Types of bonding
The periodic table is organized in columns, called groups or families, and rows, called periods.  There are several groups or periods that have specific names.

There are general characteristics of each type of bonding:

Bond Polarity
When nonmetals bond covalently with a large difference in electronegativity, a polar bond is formed.  A polar bond has a partial separation of charges.  Polar bonds are symbolized with an arrow pointing towards the more electronegative element and a crossed tail by the less electronegative element

Valence Shell Bonding Theory
The Valence Shell Bonding Theory assumes that bonds are formed when atomic orbitals overlap.  Direct overlap leads to sigma bonds and parallel overlap leads to pi bond. 

Atoms chemically bond together to form molecules.  This tutorial introduces the types of bonds that occur, and the most simple bonding theory—Valence Bonding Theory.
