What it does
Ptable presents chemical elements with selectable properties, units, electron configurations and isotope information.
Select the property you want to compare before moving among elements. The interface distinguishes quantities such as melting point, electronegativity and density, with units shown beside them. The isotope controls answer a different question from the standard element view. Keep the selected quantity and unit in your notes when comparing values.
