What is Ptable?

Ptable is a fast, interactive periodic table that lets you colour elements by melting point, electronegativity or other properties, explore electron orbitals and isotopes, and look up common compounds. It works in many languages, has a dark mode and is free to use in the browser.

Pros: what Ptable does well

  • Rich property views
  • Fast and clean
  • Isotopes and compounds built in

Cons: where it falls short

  • Focused on chemistry only
  • Dense menus at first

Who Ptable is for

Chemistry students and teachers who want a better periodic table than the poster on the wall.

Who can skip it

People who only need an element's symbol now and then.
