{{Navbox periodic table}}

Column counts are columns only that contain elements. "Compact" denote cells with element symbol only, have navbox style and the table fits basic wiki page width (1024×768). "Large cells" have more data, and may cause page width excess (scroll bar added). "Extended" periodic tables are about theoretical periods 8 and higher.

Table forms

Standard	18 columns: {{Periodic table}} (regular cells with names; common standard) {{Large cells}} image:Periodic table 32 columns: {{compact cells, navbox style}} {{Large cells}} {{Micro cells}} {{Micro cells, as infobox}}
Extended	by Aufbau: {{50 columns, compact}} {{50 columns, period 8, compact}} by Fricke: {{52 columns, large cells}} {{32 columns, compact navbox style}} by Pyykkö: {{periods 8–9}} {{superactinides in period 8}}
Alternative structure	{{Left Step (Janet)}} {{Compact}} {{With filling sequence per row}}
