Technetium Element in Periodic Table | Atomic Number Atomic Mass

Technetium Element:

Technetium is a chemical element and it is a member of group 7 and period 5 in the periodic table. The atomic number of Technetium is 43 and it is indicated by symbol is Tc. Tc  located between rhenium and manganese in the seventh group. It is a silvery-gray radioactive metal with an appearance similar to platinum. It is dissolves in nitric acid, aqua regia and concentrated sulphuric acid. The most stable isotopes of technetium are ⁹⁷Tc, ⁹⁸Tc and ⁹⁹Tc.

Uses Of Technetium Element:

• Technetium is used in steel alloys
• Technetium-99m is widely used for medical diagnostic studies
• Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
• It is also an excellent superconductor at 11K (-439.9 F / -262.1 C) and below.
