Periodic Table

It's the International Year of the Periodic Table!

2019 is the 150th anniversary of the creation of the Periodic Table, in 1869, by Dmitri Mendeleev.

This page creates a flexible, resizable Periodic Table of Elements on the fly. Every cell is linked to its element's Wikipedia page.

Selecting a text size 20 pixels or larger will produce a fully-featured periodic table suitable for printing and display - including borders, group and period labels, and atomic masses.

Printed periodic tables often save space by showing the Lanthanides and Actinides separated out below the main body of the table. In order to show them in their correct group positions, check "Long Format".
