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).
