Chemguide: Electronegativity
This page explains what electronegativity is, and how and why it varies around the Periodic Table. It looks at the way that electronegativity differences affect bond type and explains what is meant by polar bonds and polar molecules.
Clackamas Community College
Clackamas Community College: Electronegativity
A good discussion of electronegativity and its effects on bond polarity and bond type.
