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.
Sources
Made by Bombarding Molybdenum with Deuterons
By-product Zirconium Refining

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.
