This site helps fill the gap. Started by Yinon Bentor as an 8th grade science project, it is a very clean and useful site on the 112 elements. You can search by atomic number, element name, chemical symbol, or date of discovery. Each element has basic information, i.e., symbol, atomic number, mass, melting point, density, color, structure, etc. There is a graphic of the atomic structure and facts such as date of discovery, discoverer, name origin, and uses.
Some elements have links to other sites with a variety of other information on the element.
