Detailed explanation-1: -Molybdenum-99, with a half-life of 65.94 hours, decays into technetium-99 through beta decay. While technetium has never been found to occur naturally on earth, its spectral lines have been observed in S-, M-and N-type stars.

Detailed explanation-2: -Technetium was created by bombarding molybdenum atoms with deuterons that had been accelerated by a device called a cyclotron. Today, technetium is produced by bombarding molybdenum-98 with neutrons.

Detailed explanation-3: -technetium (Tc), chemical element, synthetic radioactive metal of Group 7 (VIIb) of the periodic table, the first element to be artificially produced.

Detailed explanation-4: -Technetium (Tc-99m) is an isotope commonly used in a number of medical diagnostic imaging scans. Tc99m is used as a radioactive tracer for nuclear medicine; which is a form of medical imaging that assesses how particular parts of our body are working or functioning.
