Periodic Table Elements
This reference covers all 118 named chemical elements, from hydrogen at atomic number 1 to oganesson at 118. Atomic number provides a stable sort key, while symbol, category, credited discoverer, and a concise identifying note support quick lookup and comparison.
Core identifiers are based on Wikidata. Discovery attributions, category labels, and the short known-for summaries are editorially condensed and can vary between references.
