 Color coding for atomic numbers:
 - Elements numbered in blue are liquids at standard temperature and pressure, Standard Temperature and Pressure (STP);
 - those in green are gases at standard temperature and pressure, STP;
 - those in black are solid at standard temperature and pressure, STP;
 - those in red are Synthetic element, synthetic (all are solid at standard temperature and pressure, STP).
 - those in gray have not yet been discovered (they also have muted filled colors indicating the likely chemical series they would fall under).
