The Periodic Table of Elements Station 1 The Periodic Table is a chart that arranges the elements according to their periodic or repeating patterns. In 1869, a Russian scientist named Dmitri Mendeleev noticed that when he arranged the elements into rows and columns by their increasing atomic mass...
A single click turns a mess of numbers into a clear trend. Diagrams can be created for all comparable characteristics. The table can display any number of diagrams and, when necessary, all but one can be disabled. This flexibility gives you complete control over what you want to compare. Yo...
