Periodic table (standard)

This is a typical display of the periodic table of the elements. For more information on its contents and history, see the article Periodic table.

This common arrangement of the periodic table separates the lanthanides and actinides from other elements. The Wide Periodic Table incorporates the f-block; the Extended Periodic Table incorporates the f-block and adds the theoretical g-block.
