This web page explains the concept of electronegativity, the ability of an atom to attract electrons to itself. This concept is key to a qualitative understanding of chemical bonds, because the type of bond formed is largely determined by the difference between the electronegativities of the atoms involved. The tutorial explores patterns of electronegativity in the Periodic Table and includes a question set with answers for self-guided study.
This page is part of Chemguide, an informational website developed by a veteran high school teacher to promote deeper understanding of concepts in introductory and intermediate-level chemistry.

4. The Physical Setting
4D. The Structure of Matter
6-8: 4D/M10. A substance has characteristic properties such as density, a boiling point, and solubility, all of which are independent of the amount of the substance and can be used to identify it.
9-12: 4D/H7b. An enormous variety of biological, chemical, and physical phenomena can be explained by changes in the arrangement and motion of atoms and molecules.
10. Historical Perspectives
10F. Understanding Fire
9-12: 10F/H5. Since Lavoisier and Dalton, the system for describing chemical reactions has been vastly extended to account for the configuration taken by atoms when they bond to one another and to describe the inner workings of atoms that account for why they bond as they do.
