Table of Elements in 2369
A chemical element was a pure substance composed only of atoms such as hydrogen, oxygen, or iron. Human scientists had only discovered 92 naturally-occurring elements as of the year 2152. (ENT: "Cogenitor", "Doctor's Orders") By the 24th century, over 200 naturally-occurring elements had been discovered, summing to 323 if synthetic elements were also included. Elements occurred in four different states: solid, liquid, gas, or plasma. Antimatter counterparts of each element could also exist. (TNG: "Manhunt", "Rascals")
When astronomers from Kelemane's species attempted to contact the Sky Ship, their radio transmission sequence consisted of prime numbers and the elemental constants. (VOY: "Blink of an Eye")
