Rhenium Element in Periodic Table | Atomic Number Atomic Mass

Rhenium Element:

Rhenium is a chemical element and it is a member of group 7 and period 6 in the periodic table. The atomic number of rhenium is 75 and it is indicated by symbol is Re. After tungsten and carbon, rhenium is the element with a relatively very high melting point compared to all the elements.¹⁸⁵Re and ¹⁸⁷Re are naturally occurring isotopes of rhenium, which is unstable but has a very long half-life.

Uses Of Rhenium Element:

• Rhenium metal is used in molybdenum and tungsten based alloys and jet engines.
• Rhenium is used as an electrical contact material.
• It is widely used as filaments for mass spectrographs.
