Tap or click any element to see its key metrics here.
All 118 known elements are stored as a static table — atomic number, symbol, name, atomic mass, and category (like alkali metal, noble gas, or transition metal) — rather than pulled from a live feed, so it works instantly and offline once loaded.
Search matches against the name, symbol, or atomic number and highlights the matching cell directly on the table, which is faster than scanning row by row when you already know roughly what you're looking for.
Clicking any cell shows its full stored details. Atomic masses shown are the conventional standard values used for general reference and classroom purposes, not a live IUPAC data feed reflecting the latest isotope-based revisions.
No — masses and classifications are conventional reference values suitable for general use and study, not a live feed from IUPAC. For authoritative research work, check IUPAC's own published tables directly.
Yes — the search box matches name, symbol, or atomic number, so typing 79 finds gold (Au) just as typing 'gold' or 'Au' would.
Atomic number, symbol, full name, atomic mass, and category (such as noble gas, halogen, or transition metal) — click any cell to see its details.
Yes, all 118 elements currently recognized are included, covering the full periodic table through the most recently named elements.
