2 Facts
2.1 Interesting Facts
  • Original name of Technetium was Masurium.
  • At the time of its discovery it found in sample of Molybdenum.
  • Hafnium metal is highly reactive, hence not found free in nature.
  • Hafnium metal as predicated after Mendeleev finished his periodic table.

3 Uses
3.1 Uses & Benefits
  • Technetium is a radioactive metal and hence it is used for medical studies and other research purposes.
  • It has an ability to absorb neutrons and hence it is used to make control rods in nuclear submarines. And this metal is also used in Plasma welding torches.
  • It alloys with iron, titanium and niobium are very useful.
