Just click on an element and more information pops up. If you dig down, you will find the history and uses of the element, its oxidation states and even some photographs and videos of the elements and their reactions. This is available as a free app for mobile phones: a must for every chemistry student!
Type in the name of a compound (e.g. aspirin) and up comes its formula, molecular mass, uses and a host of other useful information including 3-D space filling structures (but be patient as this can be slow loading) and IR, NMR and Mass spectra. Another comprehensive database for organic compounds is to be found at: http://sdbs.db.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi
First port of call for data on elements and compounds. Provides spectroscopic and thermodynamic data, including standard enthalpies of formation and standard entropy.
