Technetium is a metal having silvery grey color. This element has physical property of tarnishing in moist air. This element is similar to element called as Rhenium. Rhenium is also a silvery white element having high weight. In 1987 the scientist was discovered the technetium is a first superconductor at 11 Kelvin and above.
