This is an extensive list of links to chemistry-related web sites. Categories of topics include University Chemistry Departments, Chemical Jobs / Careers, Chemical Companies / Industry, Chemical Literature & Publishing, Chemical Information (conferences, databases, dictionaries, mailing lists, etc), Chemistry Software, Organizations, and Topics (analytical, biographies, chemicals, electrochemistry, environmental, organic reactions, radioactivity self-assembly, etc.). You can also do a keyword search through their resources. (Maintained by The University of Liverpool, Department of Chemistry.)

Take a look at this interactive periodic table of the elements! Click on the element symbol for more information about the element. You can choose to view the table with the following displayed: element names, atomic numbers, atomic masses, electron configurations, number of neutrons, melting and boiling points, dates of discovery, or crystal structure. Or, view the elements by group (like Alkali Metals, Transition Metals, Metalloids, and Halogens for example). (Maintained by Lawrence Berkeley National Laboratory.)

This site has many useful resources for general chemistry students: a database of common compound names, formulas, structures, and properties; notes and guides for first semester general chemistry; articles and tutorials (on topics like separation technologies and molecular basis of flavor); tools (like graphing, popup tables, and calculators); quizzes and drills; glossary; and MUCH more!
