technetium (pronounced tek-NEE-shi-um) is a transition metal
has a silver-grey color similar to platinum
density: 11 grams per centimeter cubed
technetium is radio active and was the first to be artificially produced
technetiumcomes from the greek word technetos meaning "artificial"
melting point: 3, 942 F & boiling point: 8,811 F
Who/How did they discovered Tc? 3 German scientists, Walter Noddack, OttoBerg and Ida Tacke discovered Technetium in 1925. However, their discovery is highly controversial because the experiment they performed. They used x-ray diffraction spectograms and calculated the wave length ratio to that of the atomic number through a formula created by Henry Moseley. This experiment has never been able to be replicated since.
How is it produced? Technetium is highly radioactive and is only found naturally on earth's crust. It is produced artificially by bombarding mollybdenum-98 with neutrons. Technetium is commercially produced from nuclear reactors and through the detonation of nuclear weapons.
