- get_element
Everything the Interactive Periodic Table knows about one element: classification, physical and chemical properties with units, electron configuration, discovery, a short summary and a longer introduction (uses, production, history, safety), plus the link to its page.
- search_elements
Find elements by symbol, atomic number, or full or partial name in any supported language. Use it when a name is misspelled, partial or in another language.
- list_elements
List elements, optionally filtered by category, block, period, group, state at 25 °C or a numeric property range, and sorted by a property. Without filters it lists all 118 elements in atomic-number order. Elements with no value for the range or sort property are left out.
- compare_elements
Side-by-side numeric properties of 2-10 elements, with units.
