Created by David D. Hsu. of the Massachusetts Institute of Technology in 1996. The Perkin-Elmer Periodic Table v2.02g was used for Atomic mass, density, volume, group, heat of fusion, heat of vaporization, specific heat, and shells. The site has been updating pages with images, YouTube chemistry clips and more.
Features a different molecule for each month, with entries available back to the site's start in January 1996. Information is submitted from members of the scientific community and range from diamond to THC to formaldehyde to aspirin. Included are history, structure, use, and description, though entries vary from author to author. The site is maintained by the School of Chemistry at the University of Bristol.
A basic, clickable periodic table. Select an element to learn symbol, atomic number, atomic weight, oxidation states, electronegativity, state at room temperature, melting point, and boiling point.
Click on individual elements in the Periodic Table for information: symbol, name, atomic number, atomic weight, group number, history and description, electronic, physical, and nuclear properties, compounds formed, and crystallography.
