A complete periodic table of elements list

Use this list when you need all 118 chemical elements with accurate names, symbols, and atomic numbers in a copy-ready format.

Looking for a complete periodic table of elements list you can copy into a spreadsheet, code file, or document in seconds? This page provides all 118 IUPAC-recognized chemical elements in strict atomic number order from Hydrogen (1) through Oganesson (118), with each entry showing the full element name, official symbol, and atomic number. The text format gives you a readable label per line — perfect for worksheets, quizzes, or reference tables. The JSON format outputs a clean array of element symbols like ["H", "He", "Li", ...] that you can paste directly into scripts, seed files, or front-end data arrays. The HTML format generates ready-to-use <option> tags for chemistry dropdown menus and form selects. All element names and symbols follow official IUPAC conventions, including correct two-letter capitalization for symbols such as Fe, Na, Au, and Hg, and IUPAC-approved names for the superheavy synthetic elements like Nihonium, Moscovium, Tennessine, and Oganesson. The list is especially useful for building chemistry apps, seeding science databases, creating educational handouts, or populating reference tables where completeness and accuracy are critical. Because the dataset covers all 118 elements with no gaps, you can rely on it for both general reference and specialized applications involving the full span of the periodic table.

All 118 elements

Covers every IUPAC-recognized element from Hydrogen to Oganesson, including synthetic and superheavy elements.

  • Atomic numbers 1–118
  • No gaps or omissions
  • Includes transuranic elements
Three copy-ready formats

Switch between text labels, a JSON array of symbols, and HTML option tags with one click.

  • Full name + symbol + number in text
  • Clean symbol array in JSON
  • HTML <option> tags for dropdowns
Accurate symbols and names

Every element name and symbol follows official IUPAC capitalization and spelling conventions.

  • Correct two-letter casing (e.g. Fe, Na, Au)
  • Official IUPAC names
  • Deterministic atomic-number ordering

Element list best practices

Keep symbols, names, and atomic numbers in sync when you adapt this data for other systems.

  • Use the JSON symbol array as the canonical machine value and store full names separately as display labels.
  • Preserve IUPAC capitalization for symbols — 'Fe' is correct, 'FE' and 'fe' are not.
  • When filtering to a subset (e.g. noble gases only), document the atomic numbers included so the scope is unambiguous.

Frequently asked questions

Does this list include all 118 elements?>
Yes. The list covers every IUPAC-recognized element from Hydrogen (atomic number 1) through Oganesson (atomic number 118), with no gaps.
Why does the JSON output contain symbols instead of full names?>
The JSON format is configured to output element symbols (H, He, Li, etc.) because symbols are the standard machine-usable identifier in chemistry data. The full label with name and atomic number appears in the text and HTML formats.
Are the synthetic and superheavy element names official?>
Yes. All names and symbols, including those for elements 113–118 (Nihonium, Flerovium, Moscovium, Livermorium, Tennessine, and Oganesson), follow the official IUPAC-approved designations.
