- Periodic table (vertical)
The alternative periodic table is a standard
periodic tablerotated counterclockwise and then mirrored across the vertical axis, so that the lower groups are to the left and the number increases to the right. Due to the rotation and the incorporation of the lanthanides and actinides into the main table, the Alternative Table is significantly longer vertically than the Standard Table. Its restricted width allows it to be read on-line without needing to scroll horizontally.
