A difficult concept for students has always been the periodic table. It is a bulky, overwhelming, confusing map that is one of the most important tools in the chemistry classroom. Once you can learn to understand and interpret it you can get a lot of information out of it.
The periodic table is one of the first few topics reviewed in high school chemistry. Students are expected to learn group names, the reasons for things being grouped together, valence shells, etc. This website places all that information in one place and in an easy to understand format.
Clicking an element takes you to a page with a description, physical information, atomic information, and other important information about the element. This website would be very useful for students in HS and at a collegiate level.
