Naturally occurring tritium is extremely rare on Earth, where trace amounts are formed by the interaction of the atmosphere with cosmic rays. The name of this isotope is formed from the Greek word "tritos" meaning "third".
The Chemical Element Discoverer located a very specific Chemical Element called the Isotope of [Tritium] and what is the name of this Discoverer?
