Technetium was the first synthetically produced element. It is a radioactive
metal that was produced by bombarding molybdenum (42), with deuterons in a
cyclotron. It becomes a superconductor when the temperature drops to 11.2 K or
below. Its properties are similar to rhenium (75). It has been said that
technetium compounds and alloys are very effective in the prevention of
