Most people believe the periodic table is the most important chemistry reference there is. All the known elements are arranges in an informative array. For that reason, the Los Alamos National Laboratory offers the Periodic Table of Elements: A Resource for Elementary, Middle School, and High School Students.
When you open the file of any element in thePeriodic Table of Elements, you will find a small table with some basic information about that element, such as atomic number, symbol, and weight.
