Periodic Table Finder

Search any element by name or symbol — free, instant, all 118 elements.

How to Use the Periodic Table Finder

  1. Search or Type: Type an element name or symbol into the search bar.
  2. Instant Lookup: The tool searches all 118 known elements instantly.
  3. Inspect Properties: View atomic number, symbol, and atomic mass.

Why Use This Tool

Looking up any chemistry element's atomic number, symbol, and mass online for free saves flipping through a printed periodic table or textbook appendix. This tool searches all 118 known elements by either full name or chemical symbol and returns the key details instantly. It offers a faster lookup than flipping through a physical chart, especially useful mid-homework when speed matters.

How It Works

This chemical-element-lookup tool searches a complete database of all 118 known elements, matching your search term against either the full element name or its standard chemical symbol, then displaying the atomic number and atomic mass. It's a free, instant browser alternative to Ptable and WebElements for a quick chemistry reference lookup.

Key Features

The atomic-weight-finder accepts either format interchangeably — search 'Iron' or 'Fe' and get the same result — making it flexible for however you happen to remember an element. As a periodic-element-inspector, the search completes instantly with no page reload, useful for quickly checking several elements in a row during homework or study. Each result now also includes the element category, period, group, and block, plus a standard Aufbau-order electron configuration for a fuller reference snapshot, with a Copy Result button to save the complete entry.

Common Use Cases

Chemistry students look up an element's atomic mass while balancing a chemical equation. Students studying for a chemistry exam quiz themselves on element symbols and properties. Teachers create quick reference materials by looking up multiple elements' properties, and science writers verify atomic mass figures while writing educational content. Trivia and quiz app builders reference accurate element data while creating chemistry-themed question sets.

Tips for Best Results

If a search doesn't return a result, double-check the spelling of the full element name, or try the standard one-or-two-letter chemical symbol instead, since the tool matches against both formats exactly. Element names and symbols follow standard international chemistry nomenclature, so unusual alternate names may not match. Bookmark this page for quick access during exam review sessions when repeated fast lookups are especially valuable.

A Quick Note

Recognizing common elements symbols and atomic weights by sight builds a foundation that pays off across an entire chemistry curriculum, not just a single assignment.
