Interactive Periodic Table
Search and filter all 118 elements, then inspect their group, period, block and electron configuration.
Tool118
The modern periodic table is ordered by atomic number. Periods run horizontally, while groups align elements with related valence-electron patterns. The s, p, d and f blocks reflect the type of subshell being filled.
Use the filters to isolate a period or block, or type a name, symbol or atomic number. Selecting an element opens a compact summary built from the same data as the 118 element pages, with a direct link to the full reference.
