What is the Periodic Table of The Elements?"It is a huge, efficient resource!"The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic...
The periodic table is a tabular arrangement of the chemical elements by increasingatomic number, which displays the elements so that one may see trends in their properties. The Russian scientistDmitri Mendeleevis most often credited with inventing the periodic table in 1869. The modern table is der...
