About Periodic Table of the Elements

This interactive periodic table lays out all 118 chemical elements in the classic 18-column grid, with the lanthanide and actinide series shown in their detached f-block rows. Each tile carries the element’s symbol, name, atomic number and atomic mass, and the tiles are color-coded across ten element categories, from alkali metals to noble gases.

A search box finds any element by name, symbol or atomic number, highlighting matches while dimming the rest of the table, and category filter chips let you isolate groups like transition metals or halogens. It is a quick reference for chemistry students checking electron configurations and anyone who needs an atomic mass without opening a textbook.

Tapping an element opens a detail panel with its group, period, block, atomic mass, electron configuration, electronegativity, phase at room temperature and category — each value copyable with one click. Everything runs in your browser, so lookups are instant.

How to use Periodic Table of the Elements

  1. Open the tool to see all 118 elements arranged in the standard periodic table layout, color-coded by category.
  2. Type a name, symbol or atomic number in the search box — matching elements light up while the rest of the grid dims.
  3. Click a category chip (for example noble gases or lanthanides) to highlight only that family of elements.
  4. Tap any element tile to open its detail panel with mass, electron configuration, electronegativity, block, phase and more.
  5. Use the copy buttons in the detail panel to grab any value, then press Esc or click outside to close it.

Frequently asked questions

All 118 confirmed elements, from hydrogen through oganesson, including the full lanthanide (57–71) and actinide (89–103) series displayed in their traditional detached rows below the main grid.

The detail panel lists atomic number, symbol, name, atomic mass in unified atomic mass units, category, group, period, block, electron configuration, electronegativity and the phase at room temperature — solid, liquid or gas.

Yes. The search box accepts an element name, its symbol or its atomic number, so typing 79 highlights gold just as typing Au or gold does. A live counter shows how many elements match.

Colors mark the ten element categories: alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides and actinides. The matching filter chips let you view one category at a time.

Yes, completely free with no sign-up. The whole table, the search, the filters and the element details run locally in your browser, so nothing is sent to a server.
