The alternate table is a periodic table perpendicularly rotated counterclockwise, hence like in many writing systems, 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 Alternate Table is significant longer vertically than the Standard Table. Its restricted width allows browsing on-line without creating an additional, horizontal web browser scroll.
Color coding for atomic numbers:
- Elements numbered in blue are liquids at Standard Temperature and Pressure (STP);
- those in green are gases at STP;
- those in black are solid at STP;
- those in red are synthetic (all are solid at STP).
- those in gray have not yet been discovered (they also have muted filled colors indicating the likely chemical series they would fall under).
