WebElements aims to be a high quality source of chemistry information on the WWW relating to the periodic table. Coverage is such that professional scientists and students at school interested in chemistry and other sciences will all find something useful.
You will find thousands of graphics showing elements structures and periodic properties here.
Currently, most information is about the elements themselves but the scope of WebElements will include simple compounds as well as more chemistry information in the future.
Note that elements 113, 115, and 117 are not known, but are included in the table to show their expected positions. Elements 114, 116, and 118 have only been reported recently.
The team of Berkeley Lab scientists that announced two years ago (1999) the observation of what appeared to be Element 118 (heaviest undiscovered transuranic element at the time) has retracted its original paper after several confirmation experiments failed to reproduce the results. This means that the pages for element 118 and parts of the data for element 116 are wrong. Please see this page for more details.
