WebToolArcExplore the table without losing its shape
Search by name, symbol, or atomic number, or filter by element category. The full periodic layout stays visible so group and period relationships remain clear; non-matches are dimmed rather than collapsing the table.
Read the selected element
Select any element to see its atomic number, standard atomic-weight value, group, period, and category. Lanthanides and actinides are shown in dedicated rows, and fullscreen mode is useful on larger classroom or reference displays.
